It’s no exaggeration to say that scholarly analysis of the Judean Desert scrolls is indebted to technology in ways unquantifiable. One of the first methodological steps that John Trever made was to use his photography skills to photograph the scrolls. Trever managed to photograph three scrolls that were brought to him at the American Schools of Oriental Research in 1947. Trever reasoned that quality photographs would enable a thorough analysis of palaeography, without having to handle the physical artefact over and over again.1 Trever’s images are priceless for scholarly analysis of manuscripts such as 1QS (The Rule of the Community) or 1QIsaa (The Greaty Isaiah Scroll).
But the history of the images does not stop with Trever. In addition to Trever’s collection, there are several other invaluable collections of images; three collections of significant note are: the Palestine Archaeological Museum (PAM), the Shrine Collection (SHR), and the Leon Levy Dead Sea Scrolls Electronic Library (IAA).2 The PAM images are indexed in a very helpful volume: Stephen Reed, The Dead Sea Scrolls Catalogue: Documents, Photographs and Museum Inventory Numbers, ed. Marilyn J. Lundberg and Michael B. Phelps, SBL Resources for Biblical Study (Atlanta: Society of Biblical Literature, 1994).3
The PAM images, in particular, are important for several reasons. These images are often earliest and thus reveal the state of the fragments within months from their having been removed from the Qumran Caves. In addition, the images served as notes to the editors4 and thus the movement of a fragments on various PAM plates can often times reveal material connections.
In this PAM image, we can see how Jósef Milik made notes about the relationship between each fragment, as he peeled each layer (= a fragment) from a wad. He even seems to have used damage caused by a “stone” that was embedded in the scroll. This is crucial information as to how this scroll would be reconstructed (1Q22, דברי משה), and how damage patterns can aid the process of material reconstruction.
It is for reasons above, that the PAM plates themselves cannot be neglected. But how might we find other fragments that could have been part of this scroll? Or how might we find where the same fragments imaged above exist on other PAM plates? For the most part, one can begin by checking Reed’s The Dead Sea Scrolls Catalogue and Tov’s Revised List, but in my experience these lists are not comprehensive. I discovered this when I was searching through the PAM images some years ago, and stumbled on a plate of 4Q266 fragments that had not been indexed. This observation prompted to work through all the PAMs, but this is a daunting amount of work to do for one person, especially when time is precious.
Thus, I decided I would harness the speed of the computer, and put it to work for me. So, I started to tag the PAM photos several years ago.6 By tagging, I mean each PAM is tagged with respect to the fragments that were imaged on it. As the following example diagram makes clear:
Since the fragments are tagged with respect to their Region of Interest on the width and height of the fragment, it is possible to use this data in Computer Vision searches. When stored in a relational database model (e.g., postgreSQL or MariaDB), it is possible to draw on the significant power of OpenCV, Sift, and Fastai to search these images in ways unimaginable. Here is a sketch of the algorithm I have authored to conduct research for my University of Toronto doctoral dissertation and scrolls research:
- Of course, Trever desired that William F. Albright, who was in the United States of America at the time, could examine the scrolls so as to validate their authenticity and date. For more information, see his memoirs, The Untold Story of Qumran (Westwood, New Jersey: Fleming H. Revell Company, 1965).
