Earlier this week we shared here a digitized Haggadah with Ladino translation and asked for assistance in identifying the edition. On the Hebrew Printing and Paleography facebook group, Noam Sienna, who will soon defend his thesis on “Making Jewish Books in North Africa, 1700-1900” came to our help and found it – an edition printed in Livorno(Leghorn) by Elia Benamozegh in 1867 (Yaari 958, Otzar Hahagadot 1292).
During these days of this highly virtual Passover, the social network is replete with beautiful scanned pages of Haggadot being shared online. A magnificent thread on Haggadot throughout the ages was twitted by Michelle Chesner while cooking for the Seder. There is also a rich variety of the digital texts of the Haggadah shared openly, for example, on the websites of Sefaria and the Open Siddur.
What is unique in our digital Haggadah?
The file we share below was created using the platform Transkribus, which enables its users not only to manually transcribe scanned image, or try to automatically identify the text, but also to train the computer to recognize text of its kind. While OCR – Optical Character Recognition software is extant for many years now, most of it is efficient mainly on standard prints of the most commonly spoken languages. Less so on historical materials, less common scripts, fonts and languages. Recent advances in machine learning enable gaining better results even with special scripts and fonts, and even with handwriting.
Using Transkribus, we analyzed and transcribed the text so that the lines of text are linked to their exact location on the page:
When the data is saved this way, it can be used as “Ground truth” – an example that is used by the computer to train on. The outcome of training is a model that can then be used to automatically recognize similar material. Using the model that was trained on the Tetouan Haggadah, we automatically read a page from the Venice Haggadah printed by Bragadin 1629. The result, though not perfect, is relatively easy to correct. with more data, better models can be trained, and the road opens to automatically read more Haggadot.
A ground truth text, moreover, can be used to train automatic text recognition not only within the Transkribus platform, but in any other tools for text recognition machine learning. The Haggadah Hebrew-Ladino ground truth is available for download here in both ALTO.XML and PAGE.XML format.
This is what we managed to find out so far: our ‘Tetouan’ Haggadah, the Jalfon family haggadah was most probably printed in the late 19th century, possibly in Livorno (Leghorn), a Jewish printing hub that produced many Haggadahs with various translations to communities throughout the world. The most similar Haggadahs we found were those produced there, and especially this copy from 1842/3, printed by Solomon Bilforti and Moses Israel Falagi:
The illustrations of the Jalfon Haggadah, modelled as many other Haggadahs on the 1604 woodcuts of the Venice Haggadah are still rather different than any other Haggadahs we found. Notice, for example, the pictures below: in the first, the Tetouan haggadah, the house on the left has no tiled roof, as is the case in the Bilforti haggadah below it, and and other Livornese Haggadahs we have seen. There are other peculiar differences to be found.
Whether it is as a fun challenge to pass time in quarantine days, for an iconographical study, or for comparison with candidate sibling Haggadahs that might reveal the edition details of the Jalfon family haggadah, all its images are available in this folder .
Well, quite a bit has changed and Passover will not be the same this year. It is an eerie occasion, yet especially appropriate, to be unveiling a digital project that aims to make Jewish Heritage digitally open and available for research, accessible beyond limitations of space, and, as it happens, of quarantine.
It is even more appropriate to start by sharing as the first digital fruit of our project a family haggadah. This specific 19th century Hebrew-Ladino Haggadah, bearing the stamp of Abraham J. Jalfon (1875-1949) from Tetouan, Morocco, arrived via Spain to Israel with Michel Jalfon, his great grandson, who is one of the contributors to this project.
There is much we do not know yet about this copy; It has lost its cover and front page and with it the information about its edition – place and date of publishing, printer and provenance. Some of this we hope to learn from you, the reading and studying community. The answer may lie in reference books on your shelves, or in similar Haggadahs in your families.
During the days of this coming Passover I will post a little about the meaning of its being a digital Haggadah and of the way in which Digital Jewish Studies can approach it, and benefit from it.
For now, you can scroll through the pages of our mysterious “Tetouan” haggadah below. It is a textual PDF which enables search, copy and paste. By clicking the << sign on its upper corner, a menu will open where you can chose to expand the view, print or download. By clicking the opposite corner, you can open or close a panel that will let you browse the pages or alternatively, navigate via a table of content.
