Strange Parallels

Title page of the 12th section of the third volume of supplements to the Nova Acta Eruditorum, Leipzig 1739.

Friday n° 50, September 27th, 2019

Historians always hope that those figures they have chosen may be taken as exemplary for a certain kind of person in a certain kind of historical situation. For only then the experiences of those exemplary figures – or the phenomena connected to them – may be generalized and may then be analysed in a typological perspective. If only it were not so hard to establish such claims to exemplariness.

It is thus always nice to come across sources arguing in the same direction as oneself. Even though it may of course be questioned whether any particular source is exemplary and how much trust one may put in its assertions, it feels good to hear a familiar judgement. Now just a few days ago I found such a source while coding references to my protagonists from the Nova Acta Eruditorum into my database.

In search for a certain Lakemacher…

The third tome of supplements to the Nova Acta Eruditorum, printed in 1739, contains a review of the 4th volume of Johann Gottschalk Clausing’s Jus Publicum Romanorum[1] in its sectio duodecima. This review lists many names of authors directly or indirectly connected to the publication – as the Nova Acta Eruditorum reviews in general are not at all afraid of namedropping – among which was, on the one hand, Adriaan Reland, as you see below (my sole reason for looking into this review at all).

Nova Acta Eruditorum, Supplementa, vol. 3, section 12, Leipzig 1739, p. 546.

On the other hand, there were many people which I had to look up since I encountered them for the first time during the course of the project. You would think that this should stop at some point, but no, these discourses were obviously quite flexible, and meanwhile I am sure that there are still more to come. Among these names now directly following upon Reland’s was that of a certain “Jo. Gothofr. Lakemacher[us]”, which somewhat unsurprisingly turned out to designate Johann Gottfried Lakemacher (1695–1736). Lakemacher, this was easy to find out, had been professor at the university of Helmstedt, where he had held the chairs for Greek and Oriental Languages at the philosophical faculty, as the professorial catalogue of Helmstedt university details.

… finding a model type

The Catalogus professorum of Helmstedt university gave no further information, so I looked Lakemacher up in the Deutsche Biographie, where there is an entry on him, and correspondingly in the World Biographical Information System, where he also can be found, this time with two short entries (see here and here). One of these now led me to Heinrich Döring’s (1789–1862) early 19th century dictionary of German theologians[2] where Lakemacher is dealt with in more detail in volume 2 (I–M). At the end of this biographical entry Döring explicitly drew the connection to Reland:

Lakemacher died, not yet 41 years old, on 16 March 1736, after he had just two years before published his excellent reference book on the liturgical antiquities of the Greeks, in Latin, and had chosen Reland’s Antiquitates Hebraeorum sacrae as his model in arranging the materials. Regarding the scope of his scholarship and the length of his life Lakemacher was very similar to this aforementioned Dutch philologist, who died in 1718 in his 42nd year. [3]

19th century divisions

This short passage from Döring is interesting in two respects. First, and that’s what I started with, it shows that Reland could, at least in Döring’s view, be taken as a model for a certain type of scholar, in this case the linguistically gifted, highly talented, and prematurely dying ones.  And second it proves that Döring, who was a very prolific writer of biographies (see his ADB entry), did know about Reland, who has no entry of his own in the “Gelehrte Theologen Deutschlands”.  Which seems perfectly understandable now following the above-quoted lines from his entry on Lakemacher: in Döring’s eyes, Reland as a “Dutch philologist” was neither a German nor a theologian, so he fell out of the scope of the book.

This is both an early example of 19th century nationalist classification, which repartitioned (and parochialized!) the landscape of intellectual history, and of 19th century disciplinary boundary-making, which did the same along other lines. Not that these demarcations were stable and went down unquestioned: in the end, Reland also got an entry in the German national biography (see here) the author of which classified him both as a German – at least implicitly, as his being Dutch was just passed over quietly – and a theologian. (More on this entry is to be found in this older post of mine.)

Back to Lakemacher

But how about contemporary connections between Lakemacher and Reland, who were temporally, geographically and intellectually quite close to each other, as it seems? Direct connections seem improbable in so far as Reland had died, also at the age of 41, in Utrecht on 5 February 1718, when Lakemacher was only 22 years of age and still studying at the university of Halle. In his Antiquitates Graecorum sacrae of 1734[4] however Lakemacher explicitly detailed the structural similarity mentioned by Döring:

In arranging the matters I have resorted to the same method which Adriaan Reland followed in his Antiquitates Hebraeorum sacris, for this seemed the most appropriate to me.[5]

Johann Gottfried Lakemacher, Antiquitates Graecorum Sacrae, praefatio, p. 8–9.

This may just testify to the currency of Reland’s Antiquitates sacrae veterum Hebraeorum, which seems to have been widely used as a textbook for undergraduates and saw four editions between 1708 and 1741,[6] besides numerous adaptions. In the preface to Lakemacher’s first publication, the 1718 Elementa linguae arabicae, his teacher, the Helmstedt professor for Oriental languages Hermann von der Hardt (1660–1746), did not compare his pupil to Reland, although he explicitly wrote that such an accomplishment as the book should directly qualify Lakemacher for a professorial post.[7]

Structural similarities?

So maybe the similiarities are indeed structural, and point to a certain type of young scholar who in the late 17th and early 18th century might attain academic honours early and then die a sudden death. The difference between Reland and Lakemacher, from my point of view, lies in Lakemacher becoming forgotten much sooner, and much more effectively than Reland. The reasons why this would be so are not yet entirely clear to me, although I assume that part of the solution might be that Helmstedt was not Utrecht, and another part in that Lakemacher as the later scholar might have come to be seen as epigonic. But the other parts I still have to figure out.

Peak Reland

References to my protagonists in the Nova Acta Eruditorum, 1732-1776

Friday n° 46, August 30th, 2019

As an Apology: Beyond the Ivory Tower…

…there is an everyday realm which does not always comply with the plans made inside the ivory tower. In my case, this meant that renovating one room to make it into a third children’s room went a bit out of control and took far longer than I had planned – which caused me to skip the post that would have been due last week already. I’m sorry, but I can promise with a clear conscience that this will not happen again. I don’t have got any other rooms to renovate. But since I’m done with that room now, here’s what I’ve found since then.

Into the forests and up into the Mountains

Well, I went back into the paper forest of learned journals, this time tackling the only one left to do for my comparative study, the Nova Acta Eruditorum, appearing in Leipzig in continuation of the Acta Eruditorum from 1732 until 1776 (technically until 1782, but there were no more issues since 1776). And to my surprise, I discovered a significant peak. I’m not sure yet if it really qualifies as a towering mountain, but at least it appears to be one if put into a diagram properly. What becomes visible here is that the Nova Acta Eruditorum took quite a liking to Adriaan Reland, who is referred to on 57 pages in the 25 years between 1732 and 1756 which you see to the right of this paragraph, dwarfing all my other protagonists. This is more than four times the number of references to the next in line, Eusèbe Renaudot, who is referred to 14 times during this period, and more than double the number of the references to all the other three combined, which total 27 for these years: Renaudot’s 14 plus 9 for Thomas Gale and 4 for Johannes Braun.

The peak in Reland references in the Nova Acta Eruditorum between 1737 and 1754, compared to the references to the other three protagonists.

The high time of references to Reland in the Nova Acta Eruditorum thus are the 1740s, and this is interesting because this is precisely the time when the patterns of references to my protagonists in all the other Journals I have surveyed so far fall into the on-and-off mode of mentioning them now and then every few years which I have labelled ‘intermittent referencing’ and which I take to indicate being structurally forgotten within the frame of the medium in question. And until 1737, when references to Reland begin to multiply again, the same pattern could be observed concerning him in both the Acta Eruditorum up until 1732 and the Nova Acta Eruditorum since then. So this might be the specific difference which I have been searching for, the difference which explains why Reland’s posthumous remembrance career has been so much more successful than those of my other three protagonists.

Why the peak?

Stating a difference is one thing; declaring it relevant another; and both are neither equal nor conductive to explaining, which again is a totally different thing altogether. So having encountered and labelled the phenomenon, how am I to explain it? Why were the people writing reviews for this Middle German learned journal so much more fond of Reland than of my other three protagonists – whom they knew, but were not really interested in – at this particular time?

Perhaps it is best to start with the content of these references. The pattern that underlies the peak is a very straightforward one: All the references to Reland take place within a specific context and are directed towards a specific work, and that is his last major publication, the 1714 two-volume Palaestina ex monumentis veteribus illustrata[1] which had already come out as a central reference focus in my analysis of the three-journal sample made up from the Maandelyke uittreksels, the Journal des Savants and the Philosophical Transactions.

Protestant Orientalist Learning

The specific context the interest in this particular book stems from was a decidedly Protestant one. The writers of the works in the reviews of which the references to Reland were made in the Nova Acta Eruditorum were either Lutheran ministers or Theologians employed as university or high school professors. The scholars in the reviews of whose works Reland was mentioned in 1740 and 1741, for example, were

They were interested in Oriental studies because such studies seemed useful to better understand the linguistic, cultural, and geographical setting of the Old Testament, ancient Israel or Palestine, the Holy Land. The Northern and Middle German Protestant universities of the time thus fostered the respective studies – of Hebrew, of Arabic, Persian, and other languages ‘Oriental’, of Biblical geography and history – and to do so, they built upon the results achieved by the scholars of the Dutch universities, among them Reland, with whom they shared much of the preconceptions of what godly scholarship and learning should be like. It surely was no coincidence that the Nuremberg publishing house of Monath in 1740 chose to reprint its 1716 pirated copy of Reland’s Palaestina Illustrata,[2] thus providing fresh copies for the German market.  

 In the middle of the 1750s this fascination for Reland’s Palaestina Illustrata waned in the Nova Acta Eruditorum, which might be connected with the shift from a theologically based Orientalism to a more secularized discipline within the German universities; but this is something to be explored further. But as it seems, this decade of interest may have been crucial to fix Adriaan Reland within the emerging discipline of German Orientalism, and thus to pull him from structural forgottenness for a while.

Ghost Edges and References

Snippet from the Acta Eruditorum, June 1711 issue, p. 269.

Friday n° 29, April 25th, 2019

If being remembered or forgotten is a function of reference frequency, of circulating information, an obvious conclusion seems to be that if you want to be remembered, you yourself should start circulating information lest you get forgotten. In scholarly contexts, this basically means spreading the word about what one is doing or has produced. This might in turn trigger references to you and your publications, discoveries, theories or other achievements which in turn might provide starting points for other references. Self-advertisement, for this and other, more directly visible reasons, has been and is part and parcel of academic communication. In network analysis, the reasons why such attempts at self-promotion were successful or not is often explained or even predicted by the structural features of the individual’s networks.

Shadowy networks

But what about the networks we are only partially able to reconstruct because of source loss? In some cases, I know that there were connections but can’t say much more about depth and nature of these connections because the source documents necessary to judge this have been lost. Any network reconstructed under such circumstances will be distorted, because the parts of it traces of which have survived as documents will be privileged over those parts where this is not the case. So what to do with the parts of the network which can only be traced as shadows, as ghosts of nodes and edges that once were?

Self-advertisement, done successfully

Let me start with a small piece of circumstantial evidence with throws one such ghost edge in my network of letters into sharper relief. In June 1711, the Acta Eruditorum published a small piece of seven pages titled “On the manuscript commentary of Blessed Jerome which exists in the library of Marcus Meibom in Amsterdam”.[1] Most of the text was composed of excerpts from the manuscript in question, but ahead of this the editorial board of the Acta Eruditorum lost a few words on how they got the paper in form of a short introduction:

“Lately the illustrious Adriaan Reland whom we already have given honourable mention in these Acta more than once has sent us some excerpts from a manuscript commentary on Job by [St.] Jerome, whishing them to be included in our Acta with the intention that scholars may by this specimen pass judgment on whether it is a genuine work by Jerome or not.”[2]  

[Mencke]: De b[eati] Hieronymi commentario m[anu]s[cri]pto in Jobum, AE 30, June 1711, p. 269.

This passage now not only fits in quite well with my overall framework of references and their valorisation in scholarly circles. It also explicitly states what I – based on studies such as that of Huub Laeven on the networks of Otto Mencke (1644–1707) and his son Johann Burchard Mencke (1674–1732), the successive editors of the Acta Eruditorum[3] – already had suspected: that either Mencke sr. or jr., or both, were in direct correspondence with Reland. Until now I just had no tangible evidence for such a connection, as the letters of all parties involved, Otto Mencke, Johann Burchard Mencke, and Adriaan Reland, have only fragmentarily survived. The letter concerning the codex containing the work in question here, the commentary on the Old Testament book of Job supposedly written by St. Jerome, the church father, does not exist anymore (at least not to my knowledge). But the easiest way to account for the passage just quoted is to assume that it indeed did exist.

Ghost edges

As glad as I am to finally have made sure that this particular ghost edge really existed, I am nevertheless aware that the basic problem context underlying this discovery has just become a bit more serious at the same time.

For on the one hand some of his surviving letters already point to Reland being a conscious and very active self-promoter who had a keen eye and good hand in picking opportunities to distribute his publications, and to this another distribution channel – that of the Acta Eruditorum – has just been added now. As there are quite a few “honourable mentions” of Reland by the Acta Eruditorum, like Johann Burchard Mencke wrote (or let write: as leading editor he has to be held responsible for anonymous texts in his journal), this prompts the question of how they were caused in the first place. As there are at least two letters by Reland to Jean-Paul Bignon (1662–1743), editor of the Journal des Savants in Paris, which deal with Reland sending Bignon his publications for distributing them amongst his French connections including review copies,[4] there is no reason to assume that something similar might not have taken place in his correspondence with the leading German scholarly journal as well as with its French model. This might seem to be supported by the rising reference frequency in the Acta Eruditorum concerning Reland between 1701 and 1711:

(Only the text pieces containing references to Reland are counted, not the total of references.)

The upward trend visible here might be taken as just the depiction of a young scholar’s rise of fame while making his way through academia. Reland had been awarded his first professorial post in Harderwijk in 1698/99, only to move to a more prestigious chair at Utrecht in 1700/01, publishing continuously. Or it might be an illustration of a correspondence successfully feeding the editorial board at Leipzig with relevant news and thus ensuring continuous reference to oneself. As I cannot say much more about the ghost edge than that it existed, but not for how long and how intensively it was used, the question has to remain open for now.

And on the other hand, the fragmentary state of the Reland correspondence has by now turned up quite a handful of such connections where there are either indications of direct correspondence and no surviving letters or one or two letters surviving, indicative of a communication channel which must originally have accommodated many letters more. As I already pointed out in one of my earlier posts, the correspondence between Mathurin Veyssière de la Croze (1661–1739) and Reland is only documented by three letters, all of which are no longer extant in the original. Given the close intersection of research interests between the two of them it is highly unlikely that there were not much more originally; but how could this be translated into a meaningful part of a network? The same is true for Johann Baptist Ott (1661–1744) the communication between whom and Reland is only evidenced by one printed letter in Reland’s second treatise on the Samaritan coins, as I pointed out here. It is also true for Marcus Meibom (1630–1711), the scholar whose manuscript was the reason for the note in the Acta Eruditorum which caused me to write this post in the first place. It is even true for another of my protagonists, Johannes Braun, as there are a few letters between him and Reland still extant but the bulk of Braun’s correspondence is also lost. This is by far no complete list, but I am determined to draw one up as far as this will be possible.  

The Chicken-and-Egg of Loss, Forgetting, and References

The question posed by ghost edges is of course how they relate to forgetting. They are clearly indicative of structural forgetting taking place, but in which way? Their presence could be seen as a natural effect of processes of structural forgetting: As someone fades from structural remembrance, his papers or letters become devalued and thus more likely to be sold off, discarded, or altogether lost. But their presence could also be the cause rather than the effect of becoming forgotten: As the papers and letters of someone become sold off, were discarded, or otherwise lost, materials are removed from the archival record which might have triggered new references had they still been there, which in turn leads to a drop in reference frequency and thus to structural forgetting. This is a new variant of the ages-old chicken-and-egg problem, so I have go to searching for additional factor which might help me figuring out if a particular shadowy part of the network is a ghost edge chicken or a ghost edge egg.

And so the winner is me, too, for I guessed it correctly.

A two weeks’ post

But one thing after the other. First, the date: this is my blog post for

Saturday, March 9th, 2019, for Friday no. 22;

I seem to acquire a bad habit of posting on Saturdays rather than Fridays. For today, my excuses are, in chronological order, a) I had to help out at my son’s school, fixing some shelves; b) I had to figure out how to clear some financial matters regarding how to pay my salary from this project in a way that some of it actually ends up with me in the end; c) my youngest daughter stubbornly refused to go to sleep this evening. Obviously I am not very good at scheduling my home office work hours, for although I started out at 8:00 in the morning, by 21:30 I had got down to a meagre seven hours of working time. And d) I made a tiny configuring mistake, messed up my calculations, and had to start all over again, ruining some two hours of work. I suspect I better had not started calculating only at 21:30, but a), b), and c) forced me to.

Going for some metrics, step 1: Gathering data

But the calculations are crucial, because that’s what I originally intended to show you. As I announced in my last post, I now have finished three-quarters of my projected sample of scholarly journals, which has taken me two weeks to complete, clean, and analyse now.

That is to say, I have gone through the digitized versions of the Journal des Savants, the Philosophical Transactions, and the Maandelyke uittreksels, of Boekzaal der geleerde waerelt (more info here), between 1700 and 1799. I have added all issues of these journals referencing one of my four protagonists in any way to my database. In numbers, this means 117 issues of the Journal des Savants, 9 of the Philosophical Transactions (yes, only nine, but I have already argued they are somewhat special here), and 89 of the Maandelyke uittreksels – or 205 journal issues in total. In going through these issues I have examined each page on which at least one of my protagonists was referenced, identified all other scholars and all publications on that page, and stored these data, too, as a basis for co-citation analysis to identify perceived epistemic communities and their changes over time. This netted me another 287 quoted publications, and another 739 scholars referred to and/or connected to quoted publications (as authors, editors, translators etc.). I must confess that I am a bit proud of having managed to completely identify close to 690 of these, or more than 90%. But today everything will be about publications, so the really interesting figure is that of 502 publications in this sample.

Going for some metrics, step 2: Setting a framework for analysis

The problem that I now got was how to deal with these data. Plain visualizing did not work out anymore to really map out the intriguing details. So it needed to be done the rough way, by calculating metrics for the sample, hoping for something interesting to turn up. The visualizations did help me, in the way of pointing out which ways to structure the relations to be investigated would likely not yield good results. I first thought I might try something like mapping ‘shared contributors’, that is, connecting publications by way of the same scholars contributing to them (as authors, editors, or translators). This turned out to be pretty useless because it only favoured large edited collections who assembled texts from many different authors. And that’s the reason why this post is not about persons but publications only; the real co-citation analysis still has to wait for a bit. So it seemed better to bypass persons for the time being and only to link publications to publications, and I did so by way of quotations, that is, two publications are seen as connected if at least one of them quotes the other. That brought some interesting results about.

Going for some metrics, step 3: Finally going for metrics!

With the framework set up to network this publication sample, it was high time (half past nine already!) to start calculating metrics. To facilitate calculation, I started with assuming the network edges to be undirected, that is, a link from publication A via a quote in A to publication B works both ways, from A to B and from B to A. I know that this might be a questionable simplification; but as this may be tested by comparison, I will set this matter aside for a rainy day when I don’t have any idea what to write in this blog for the week to have the opportunity to at least redo these calculations for directed edges. (And as I once started tracking time in this post, it is now 4:00 in the morning and high time that I get to bed to have at least some sleep. I’ll continue around noon.) Moreover, as the structure of connections within what one takes to be a network depends on what the question is, and I am interesting in tracing perceived epistemic communities here – that is, publications seen as belonging to shared domains of knowledge – edge directionality is less important than it might be for other questions to ask. (This is a piece of midnight reasoning, but it still looks sound now at 10:30 on the day after.) I could as well also have collapsed the journals into edges connecting the rest of the publications to more explicitly claim this, but I wanted to also get an impression of the position of the individual journal issues, and so I kept them as nodes. Admittedly, this model does have the drawback that relying on quotations only provides only a quite simplified picture of the interconnections structuring domains of knowledge, but it should serve to give a good first impression of the sample’s general structure. Having sample and model settled, I used the opportunity to test Nodegoat’s analysis functions and calculated some metrics.

A lot of numbers

To keep the scores comparable across different metrics, I chose to normalize them where possible. A short look at the visualization (see header for larger picture) made clear what was to be expected: the network is disconnected. Not all publications are referred to as situated in overlapping domains of knowledge; some are distinctly separate from the rest. This is important here because it directly impacts the calculations of the closeness metric. Closeness serves to indicate how close any given node is to all other nodes in the network. In mapping out shared domains of knowledge this might be quite interesting, as nodes with low closeness scores might be supposed to partake of many fields at once being referenced in differing contexts, and thus be important to look at. But closeness measures path lengths to calculate the average distance from node X to all other nodes, and this does not work in disconnected networks (because two nodes between which there is no path would be at undefined = infinite distance from each other). Nodegoat provides a workaround to that by substituting a maximum distance for path length between unconnected nodes, this maximum being equal to the total number of nodes in the network.[1]

First: Betweenness

The first measure I calculated was betweenness[2] (because of the problems with closeness). Betweenness works on disconnected networks and thus was the obvious first choice. Roughly put, betweenness serves to indicate whether a certain node may be considered a gatekeeper, that is, if it is situated at a vital connection point in the network. In assuming an undirected graph, for mapping shared domains of knowledge this resembles closeness: it should point to publications situated at the intersection of several domains, and thus of potential importance for each of these. I must qualify this as ‘potential importance’ because only being situated between different fields of knowledge does not equal making important contributions to any of these fields; this will have to be cross-checked with other metrics, then.

Top 10 Betweenness

These are the top ten results in terms of betweenness for the whole of the network:

And those are the respective results for the top-scoring publications of/connected to:

Adrien Reland, by Betweenness

Eusèbe Renaudot, by Betweenness

Johannes Braun, by Betweenness

Thomas Gale, by Betweenness

What becomes directly apparent is that there are a lot Reland’s publications in the network, not only on vital connection points but also in total. In fact, 37 out of 287 non-journal publications have Reland as their main author/editor, or 12,9 %; the number does matter because I only added publications to this sample when coming across a quotation within the sample. Compared to 2.8 % for Eusebè Renaudot (8 publications), 1.7 % for Johannes Braun (5 publications), and 1.4 % for Thomas Gale (4 publications) this looks even more impressive. But a large output as such does not tell anything about the quality or the reception of that output. There also is one publication by Eusebè Renaudot among the top ten in betweenness, too.

Second: Closeness

As already said, the closeness scores for this sample are to be taken with a grain of salt because of the disconnectedness workaround implemented in Nodegoat. But the prediction I theoretically made when thinking about betweenness in this network – that it would line up quite closely with closeness because pointing to structurally similar positions within the network – did come true in looking at the results for closeness, so I am tempted to regard these results as usefull still. Important: The first score in the “A” for Analysis column is always the one discussed!

Top 10 by Closeness

The top ten publications of the network in terms of closeness scores are:

This again underscores the relevance of Reland’s publications within the network as a whole, and especially of his Palaestina Illustrata.

And those are the respective results for the top-scoring publications of/connected to:

Adrien Reland, by Closeness

Eusèbe Renaudot, by Closeness

Johannes Braun, by Closeness

Thomas Gale, by Closeness

Third: Degree

In undirected graphs such as this, Degree just counts the number of connections any given node in the network has. To be precise, Nodegoat counts the number of all edges starting from and ending at any given node, allowing for duplicates edges, thus producing high scores on average.[3] For an analysis of shared domains of knowledge as proposed here Degree should be relevant as a corrective. Whereas Betweenness and Closeness both point to structural positions of publications in regard to their location between domains of knowledge, Degree points to the importance of a given publication at this structural position. Or, to put it more precisely, to the attention generated by the publication in question, as I am focusing on quotations made by scholarly journals to this publication; and many such quotations do not necessarily point to the scholarly but in any case to the public impact a work made.

Top 10 by Degree

Looking at the Degree scores from this perspective makes clear that while Reland’s publications might share in more domains of knowledge, within their respective domains Renaudot’s publications obviously attracted comparable attention. And looking at the respective results for the top-scoring publications of/connected to Johannes Braun and Thomas Gale in comparison makes clear that they were not only tied more closely to special domains of knowledge but also attracted less attention by the journals in question, perhaps because of this more stringent specialisation. So here are the Degree scores for publications divided by individuals:

Adrien Reland, by Degree

Eusèbe Renaudot, by Degree

Johannes Braun, by Degree

Thomas Gale, by Degree

A cautionary note: It does not pay to put too much trust in Degree scores, because they tend to push publications situated within certain reference patterns. Consider the example of Mathurin Veyssière de la Croze’s Lexicon aegyptiaco-latinum, the Coptic dictionary edited and published by Karl Gottfried Woide in 1775 which has already featured in one of my posts.

With a Degree of 33 it scores shortly below a top 10 place in Degree which, following the reasoning laid out above, should indicate its importance for its particular domain(s) of knowledge – it attracted a lot of attention, because it has a lot of quotes. But all of these quotes are in fact derived from one singe journal issue, the June 1774 issue, part one, of the Journal des Savants, as becomes visible from the cross-references section of its database entry.  

And there it assembles all of these quotes because it features in many different respects in the announcement written by Woide himself to highlight his upcoming publication, which makes the reference section of this piece look a bit monothematic:

Snippet from the references contained in Woide’s publication announcement

So while Degree may be taken as an indicator of importance within a given field by capturing public attention, this is easily manipulated, and has to be cross-checked against another metric for validation.

Fourth: Pagerank

Nodegoat allows for calculating Pagerank scores, following the original Google algorithm. As Pagerank was originally invented to determine the relative importance of information sources (in this case, websites) in a network through which a user might randomly move, this model might also be applied to domains of knowledge in a web of publications, treating quotations as paper-borne hyperlinks. Random movement through the graph is facilitated by its undirectedness, so please keep in mind that modelling it as undirected may be a questionable decision, and don’t trust these metric too much. The good thing about Pagerank is that allows for determining both the relative importance of quoted publications and of quoting journals in this particular configuration, so I would like to use it to counterbalance the shortcomings of Degree pointed out above. In running Pagerank, Woide/la Croze’s dictionary disappears from the leading places all of a sudden, so this seems to work. The top publications according to Pagerank thus are:

Top 10 by Pagerank  

Surprise, surprise: The main hubs for distributing quotes – and thus sorting domains of knowledge – are journals! Makes me almost wonder why I chose to go by them in the first place… But more interesting in here is that there one publication from the 287 quoted works in the sample which managed to get a place in the top 10, and that is – surprise again! – Reland’s Palaestina Illustrata. This in turn is due by it being quoted by a number of journal issues (from all three journal series) which are themselves important quotation hubs, as becomes evident when looking at the cross-references to Palaestina Illustrata, that is, the publications in the sample linking to it.

This looks as if Pagerank indeed might be a good tool to determine the importance of a publication at its respective structural position, at best in combination with Degree (and Palaestina Illustrata scores high on both). So what about the top scores for the rest of the field?

Eusèbe Renaudot, by Pagerank

Johannes Braun, by Pagerank

Thomas Gale, by Pagerank

Combining metrics

Well, that was a lot of tables, numbers, and scores. Well done! Only a few more to go. Now the last thing to do is to find a way to purposefully combine the different metrics results assembled so far to draw something relating to my larger research question from it. To do so, I ventured for a first try to identify the top 5 publications of each of my protagonists by comparison of the results I presented above. This yielded the following table[4]:

Creating a Shortest Path Matrix

To fuse this into something more informative I thought I might utilize a special function of Nodegoat’s, and that is its ability to calculate shortest paths between given selections of nodes. In this case, this meant that I first settled on a matrix of four times four publications: The top 4 publications after comparing the scores of all metrics for each of my four protagonists. I chose to use the top four because only four of Gale’s publications made it into the sample, and this provides better comparability then. Now I used the Shortest Path function to calculate the length of the shortest path through this network from each of these publications to each other, and set the results down in form of a matrix.[5] It looks like this.

Conclusions

What does this tell me now? Well, first of all it highlights the isolated position of some of these publications, which obviously do not share domains of knowledge with others; this is true for the five marked with grey lines which have no connections to the rest of the matrix. It moreover points to the broader diversity of Reland’s publications compared to the rest of the network: His four publications all have connections within the matrix, while for Renaudot one publication does not and for Braun and Gale two publications each. Reland’s and Renaudot’s oeuvres and positions are similar in that both are internally coherent – the smallest paths to those of their own publications connected to the rest of the matrix are two each – and well-connected: their publications are not only connected to more of the rest of the matrix, they are also connected by shorter paths, making their works appear to be more central. Braun and Gale on the other hand are similar in having less many publications connected to the rest of the matrix, and in those publications being situated in strongly differing fields, as indicated by their larger internal distance from each other compared to Reland and Renaudot. And both of them are on the outskirts of the network rather than in the centre as indicated by the long shortest paths to other publications in the matrix.

This buttresses the claims I have brought forward based on other impressions already: That Reland and Renaudot form a comparable pair of actors, as Gale and Braun do; and that Reland seems to be the most versatile of all four, which might be the reason why he was the last of the four to get forgotten. And, as I already suspected last week, that his Palaestina Illustrata might be more relevant for this process than his other works, even if they are better known today (as his 1705 De religione mohammedica for instance).

But this has been a fairly static picture of a phenomenon spanning one century, so the next task will be to dynamize it. Work to do!


[1] So in looking at the closeness scores in the following, always keep in mind that the maximum path length taken into consideration is 502.

[2] With duplicated edges taken into account and weighted according to distance, that is, duplicates add edge length.

[3] And Nodegoat does not automatically normalize Degree centrality. But this is an easy operation: If you want to do so, just divide any absolute Degree score by the total number of edges in the network, in this case, 2577.

[4] Publications marked in red only appear once in the table and are therefore discounted from further  comparison.

[5] Please keep in mind that shortest paths are elongated in my setting because two quoted publications A and B are (almost) always connected via a journal in between, so the usual shortest path possible between A and B is two links (A –link one– Journal  –link two– B).  

Work in Progress

Saturday, March 2nd, 2019, for Friday no. 21

I am very sorry, but I will have to postpone what I originally intended to post here yesterday for one week. The idea I had in mind does work, but it takes a lot more time to set up the calculations in detail than I had thought, and it will keep me busy for a few days still. In one of my former posts I preliminarily explored a data set still uncompleted at that time, consisting of all references to my four protagonists in the Journal des Savants, the Philosophical Transactions, and the Maandelyke Uittreksels, of Boekzaal der geleerde Waerelt during the 18th century. As this set is completed now*, it will be interesting to see what might be learned from it.

One preliminary finding – which at the same time is a hypothesis to be tested during the next days – is that in terms of being posthumously referenced it seems to pay for a scholar to diversify his research interests, or at least to offer works which may feed into many different research interests over time. For it seems that the most prominent work written by my four protagonists over the course of the 18th century turned out to be Adrien Relands 1714 two-volume “Palaestina ex monumentis veteris illustrata”. And from the contexts of the references targeting it this seems most likely to be due to its ability to be utilized for the purposes of History, Theology, Geography, and Philology alike. The downside of this is that it seems very difficult, if not outright impossible, to determine which kind of work might be suited to such purposes when writing it.

But more about this next Friday!

*At least for the moment. Next addition will be Acta Eruditorum/Nova Acta Eruditorum. To be continued!

A Palmyra-Shaped Dutch Blind Spot?

A short network animation of all references to Johannes Braun, Thomas Gale, Adrien Reland and Eusèbe Renaudot between 1750 and 1765 in from the Journal des Savants, the Philosophical Transactions and the Maandelyke uittreksels, of Boekzaal der geleerde waerelt, as moving four-year averages. Mind that Reland provides the only link connecting the Boekzaal references to the JdS-PT references.

Saturday, February 9th, 2019, for Friday Nr. 18

I have been busy adding another journal to the dataset I briefly discussed here two weeks ago; this time, it’s the Maandelyke uittreksels, of Boekzaal der geleerde waerelt taken from Hathi Trust again for a Dutch perspective to complement the British and the French already in there. In doing so, I noticed an absence that makes me wonder about its possible causes.

I already wrote here about how the rediscovery of Palmyra and the decipherment of the Palmyrene inscriptions played into my research question as it illuminates how references to structurally forgotten scholars can be used to improve one’s own standing in the Republic of Letters. Both Jean-Jacques Barthélemy (1716-1795) and John Swinton (1703-1777) had been building on research carried out, among others, the Dutch philologist Jacob Rhenferd (1654-1712) and two of my persons of interest, Eusèbe Renaudot (1646-1720) and Adrien Reland (1676-1718). Which meant that after a period of comparative absence those names, for a while, became current again as part of the discussion over the decipherment of Palmyrene. As I had already came across this discussion in both the Journal des Savants and the Philosophical Transactions, I would not have been surprised to find a similar increase in references to these names in the Boekzaal der geleerde waerelt also.

There was a significant increase in references to Adrien Reland in the Boekzaal in the 1750s and 1760s; but none to the other proponents of the debate. To make up for this, Johannes Braun (1628-1708), who had been almost completely absent from the former dataset, was mentioned much more frequently than I would have thought during this period.

Upon closer inspection, the respective entries reveal that – as it seems – the Palmyran debate just did not place in the Boekzaal. I cross-checked for references to Swinton and Barthélemy without connections to my protagonists but did not find anything related, either. Given the interest displayed by Dutch oriental scholars and philologists in Palmyrene following the first re-discovery of Palmyra for Europe’s Republic of Letters in the 1690s, that there should be no reaction at all to the second re-discovery in 1753 is a bit puzzling.

So I look around a bit and went through Delpher, the Dutch National Library catalogues, and the STCN, and found nothing much in connection. The only directly Palmyra-related Dutch publication in this time seems to have been a (pirated?) print of Joseph Jouve’s (1701-1758) 1758 novel “Histoire de Zénobie, impératrice de Palmyre” which went off Nicolas van Daalen’s press in Den Haag.  And that was not even in Dutch. Intra-textual references seem to have been as scarce, as far as Delpher is concerned (query results are here). My query only returned four publications during that time: one a geographical work set us as a fake travelogue – the first volume of Joseph de la Porte SJ’s (1714-1779) “Voyageur français”,[1] translated into Dutch as “De nieuwe reisiger; of Beschryving van de oude en nieuwe waerelt”, and the other three parts of a work of similar kind, the “Tafereel van Natuur en Konst” which appeared in 21 volumes between 1769 and 1784 in Amsterdam, a translation from an English model (volumes 1, 10, and the index volume 21).

The most curious of these is “De nieuwe reisiger”, as Jean-Jacques Barthélemy is indeed referenced in it as part of the description of Palmyra, but in a weird way.  After describing the ruins, the fictive letter-writer tells his fictive addressee “that it would be desirable that one or other scholar would try to discover the beginnings of this language, which is completely forgotten.*”[2] Added to this was a footnote indicated by the asterisk running “The abbé Barthélemy has not yet made this renowned discovery public, which justly had won him the respect of all the learned in Europe […]”.[3] Now de la Porte’s French original – which has the same passage –[4] was printed in Paris in 1765, while the fictive letter just quoted from is dated to 1736. And Barthélemy’s lecture at the Académie des Inscriptions et Belles-Lettres was printed in Paris in 1754.[5] So while the fictive letter-writer in de la Porte’s text could not have known about Barthélemy’s discovery in 1736, both the French author and his Dutch translator could – and perhaps should – have known that this discovery was very public already in 1765.

Coupled with the absence references to the debate in contemporary Dutch-language literature (as far as I was able to make out so far) this points to that the issue, while being a scholarly polemic in France and Great Britain and well-covered in German learned journals,[6] seems not to have been of much interest to the Dutch public. The next reference to it in a publication in Dutch was made – again – in a travelogue, only this time a real one. When the Swedish Arabist and Oriental scholar Jacob Jonas Björnståhl (1731-1779) went on a rather prolonged Grand Tour through Western Europe and via the Mediterranean to the Near East, Istanbul, and Greece in 1767, he wrote letters to the Swedish publisher and librarian Carl Christoffer Gjörwell (1731-1811) who collected them. They went to print in a German edition in 1772, followed by a Dutch translation in 1779; the Swedish edition only was printed from 1780 on.

Now Björnståhl described (in the Dutch translation) in his “J.J. Björnstähls Reize door Europa en het Oosten“, volume one, in a letter from Marseille, 18 November 1770, how he met Jean-Jacques Barthélemy in Paris. He rated Barthélemy’s kindness towards other scholars “higher even than the new and grand discovery by which Mr. Barthélemy has made himself known to Europa, that one can recon from him, who was the first to teach Europe so, the time since when it is possible to read Phoenician and Palmyran inscriptions”.[7] As a curious by-note to this I may add that Björnståhl five years later, in a letter dated Oxford, 10 October 1775, reported that he had also met John Swinton: “I shall conclude my letter with Mr. Swinton. This man is, as is well known, famous for his writings concerning old, and foremost Phoenician inscriptions and coins, which can be found in the English Transactions.”[8] Björnståhl said nothing about Swinton’s role in the Palmyran inscriptions’ controversy.

Adding to these findings that the debate was framed by some of its actors as a struggle for national honour in claiming the first discovery, most of all by John Swinton himself who complained about being subject to attacks by French writers, and recognized as such by others, for instance the German learned journals, it might have fallen out of the Dutch learned discourse of the time because of this national framing which did not include Dutch elements – or, as was the case with Rhenferdt and Reland, not in prestigious roles.

Yet this did not cause a lack in references to especially Adrien Reland in the Boekzaal der geleerde waerelt during this time. Not only where such references there, they also pointed frequently to the same publication, his last major work “Palaestina ex monumentis veteris illustrata”, a two-volume description of the Holy Land as taken from classical sources; they only related to it in connection with other issues. So maybe the supra-national character of the Republic of Letters really was under stress from nationally framed discoursed below the surface already, and the Palmyran discussion might be a point to illustrate this.

Proof of Concept

Monday, January 28th, 2019, for Friday No. 17, January 25th, 2019

Apologies first: This post took me a little longer than usual, I’m two and a half days late now. This is due to what I wanted to present here: The first two completed data sets for the tracking of processes of forgetting in the humanities from my project. And finishing the second one took me about 18 hours longer than I had planned. You never know what’s in the sources beforehand…

Data Sets

But now these two sets are done and ready to be presented – at least, a rough oversight of the yields of these collections. What I have done here is going through two journals, the Philosophical Transactions and the Journal des Savants, from 1700 until 1800 (well, in the case of the Journal des Savants until 1792). I went through two digitized Hathi Trust collections to be able to use fulltext search, so for everyone who’d like to check on my results, here you go: Journal des Savants and Philosophical Transactions. The few missing issues were added using other similar Hathi Trust collections. I entered all issues bearing references to my four protagonists into my NodeGoat database, identified all persons co-cited with my protagonists in these instances as good as possible, and also all publications cited therein which gave me lists like these here.

December issue of the Journal des Savants, 1782, Reference to Eusèbe Renaudot and co-citations

To fully explore these datasets will take me some time still, but I do already have some preliminary findings to share.

First: Comparability

There is an obvious imbalance between the two journals regarding coverage of my protagonists. The Journal des Savants returned 117 issues with matches, while the Philosophical Transactions returned 8. Yet this is obviously caused by their asymmetric schedules: While the Journal des Savants appeared weekly from the start and monthly later on, the Philosophical Transactions appeared once a year, or once every two years. So to make for a better comparison, the Philosophical Transactions issues cover 12 years between 1744 and 1771, while the Journal des Savants issues cover 54 years between 1702 und 1789. And while the Journal des Savants data set includes about 4,5 times as much issue material over time, these individual issues are richer in both references and co-citations than the Philosophical Transactions issues are, although the exact factor still has to be determined. Overall, the Journal des Savants was definitely much more interested in the results of my protagonists over time than the Philosophical Transactions ever were. Not that much of a surprise, one might say, given that both journals were active in different areas of knowledge production and that the Philosophical Transactions were much more interested in natural philosophy than in what we would today call humanities’ research (as I already discussed some time ago). So please keep this in mind for the following visualisations.

Second: Visualisations!

The combined datasets in full extensions: The complete network of references from 1702 until 1789. Directly visible: Three of my protagonists, Thomas Gale (bottom left quadrant), Adrien Reland (bottom right quadrant), and Eusèbe Renaudot (middle of top half) do have their quite separate circles of references with a shared overlap in the middle.
The full extension of the Journal des Savants dataset: The complete reference network from 1702 until 1789. Directly visible is a much weaker position of Thomas Gale (top right quadrant), and an enhanced position of Eusèbe Renaudot (bottom left quadrant).
Full extension of the Philosophical Transactions dataset. Directly visible is that it is much smaller, contains less references to authors (therefore smaller red circles), and that there is no connection between a shared reference network of Thomas Gale and Adrien Reland on the left and a much smaller Eusèbe Renaudot network on the right hand.

Moving pictures!

A diachronic visualisation of the combined datasets in (something like) moving ten-year-averages for the time in which they overlap, 1740 until 1779.
The Journal des Savants dataset in simple ten-year-averages from 1702 until 1789. The most interesting thing is that this dataset allows you to directly see the falling apart of a once shared reference network from the 1760s onwards. As this is precisely what I want to track and show in this project, I take this result for a preliminary proof of concept: It actually seems to work, if only within a certain framework as I already had supposed (cf. the combined dataset video where this does not become apparent).
And, last but not least, the ten-year-average visualisation of the Philosophical Transactions dataset also, which directly allows to see the huge differences between both journals regarding my protagonists.

To preliminary conclude

This rather fast overview over my first two completed data sets conveys two messages, I think: First of all that a rather more thorough exploration in terms of statistics and metrics is necessary to put my preliminary findings on a firmer basis, and second, that – and these are my preliminary findings for today – my system and framework actually does seem to work. While this is great, it poses a lot of new questions as to the framing: Can both data sets be acutally merged together as I did in the combined visualisations? Or are they so different that such combinations are of no use? And if they are, where do these differences come from? Different perspectives on science? National and/or confessional framings, as might be indicated by the very different weights of the English and Anglican Cleric Thomas Gale and of the French and Catholic Cleric Eusèbe Renaudot in both sets? Or something in between, or something third? 

Where Journals Lead, I Shall Follow…?

Saturday, December 21st, for Friday No. 11, December 20th, 2018

This is the last one! No, not the end, it’s just the last one for this year, as I’m off for vacation from – what was it – ah, now. But only until January 2nd, so come next year, come new research posts.

This should be a good time to reflect upon the state of the project so far. And to take some time to see what might still be changed for the better. So what I want to present you today is no fully-fledged piece of research but rather some thoughts on the limits of the project as it stands now.

What it’s all about

To sum it all up in a few lines again, my aim was (and is!) to work out the patterns that emerge as remembrance fades and structural forgetting sets in. More precisely, I wanted to show these patterns for the societal subset of what I call the academic metier, and for humanities’ scholars whose memory faded. To do so, I follow four specific scholars – Thomas Gale of Cambridge, Johannes Braun of Groningen, Adrien Reland of Utrecht, and Eusèbe Renaudot of Paris – and track the frequency of references to them across the centuries after their deaths. For when such references dwindle and their pattern changes from one of being frequently referenced to one of only intermittently being referenced, structural forgetting can be actually made visible.

This was my basic assumption at least, and I still think that it is sound in principle. I am using a relational database and network visualization program, NodeGoat, to gather my data and visualize them diachronically, and by now patterns really do start to emerge. The question now is: Which patterns are these?

References and framing categories

I already hinted at the problem of measuring the frequency of references to a dead scholar. Of course citations and quotations can be counted – but within which kind of frame? For early modern scholarly communication, there are basically three categories of materials still available for me: letters; publications (both manuscript and print); and journals. Everything else is either no longer extant or not available in accessible format. Perhaps auction catalogues provide something like a three-point-fifth category – they survive as printed books, so basically they are publications – but that is about it.

Letters…

Now each of these categories is tricky. Letters only survive in some cases, and in those cases then most often too many survive to make it possible to scan them all for metadata such as “mentions person X”. There are projects like Early Modern Letters Online, ePistolarium, Mapping the Republic of Letters, Electronic Enlightenment and such, but they either do not fit my timeframe or do not provide the information I am looking for. So while it is crucial to keep an eye on letters wherever possible, I cannot do so in a systematic way. Which means that I will only with great care be able to extract intermittent reference patterns from this part of my data set.

Publications…

Publications do survive in massive numbers, and in massive numbers are electronically available and searchable by now. Countless digitization projects have made available masses of material. Yet the masses produced are always larger still. There is still so much out there which is not digitized, and which I therefore would have to search in a library and go through manually, that I will not be able to establish a suitable framework for my reference patterns this way, too. Even if I reduced my research to a certain discipline, area, or language, it would still be an insurmountable task. And most of it would be very frustrating, too, because the majority of these books – by far! – would not contain any references to my four protagonists (and presumably the more so as I advance in time towards today). So while I will use all means of automatically extracting information from publications that there are to find references to my protagonists where I don’t expect them, I cannot claim to establish something like a representative sample this way.

Journals…

Which leaves me with journals, as it seems. And journals certainly do have many advantages compared to my other two sources types. First of all, they do survive in sufficiently complete form as to make general inferences possible. We know with great certainty which journals there were, and most of them survive. Second, they have been subject of lots of research by now, so that their relative importance and their outreach can be determined at least fairly well, and their workings and peculiarities are known to a large extent. Third, they are – at least the larger and more important ones – available in good editions, either in print or digitally, and thus searchable (via index or query). So I can draw up a sample of important journals for the fields, times, and places I am looking at, go through these journals, and have a data set which allows me to really infer reference frequencies for the first time. Or, given the only very partially comparable character of these early modern and 19th century learned journals, several data sets most probably. Reference spikes in the journals then would point me to the relevant developments in the reception of my protagonists.

Journals?

This does work. I found John Swinton this way (Philosophical Transactions are already done up to 1800, which was easier as thought because they only contain very few references of interest to me, fewer even than I thought they might). And, to give a less obvious example, I found the dead predikanten of the 1730s this way who by their obituaries gave occasion to reference Johannes Braun.

Everything alright, then? I frankly don’t know. It somehow doesn’t feel alright. I can only do a certain number of important journals, and I am not completely comfortable in just going where they point me. It feels a bit like being told what to do. And I am not sure if I want my enquiries directed by anonymous journalists three centuries gone. Well, time to think about it.

Have a good time, and see you next year!
