My trip to the University Library at Cambridge was successful, and they did let me in. I was able to get photocopies of the Baehrens GCS edition of Origen’s Homilies on Ezechiel. Mind you, it cost 15c per page, which made it costly and prevented me from copying the whole volume. I wish someone with borrowing privileges would scan all these early GCS editions — they’re all out of copyright.
I also took a look at the CSCO edition of Agapius, by L. Cheikho, from 1912. I’m not all that impressed by this; if it is using al-Makin to supplement the text then it doesn’t really say so. The apparatus seemed rather feeble to me. It does seem to me that a modern critical edition of this text is required. Modern technology such as multi-spectral imaging should allow the material that was illegible in those days to be read with relative ease.
Some time ago I discussed the Arabic life of the 4th century Coptic churchman Shenouda. This is of interest because it contains, improbably, a version of the Didache. It was printed with a French translation in several versions by Amelineau, over a century ago. Unfortunately all of these are offline. CUL did have the Vie de Schnoudi volume, but had consigned it to the dungeon which is the “rare books” department. This means that you can’t photocopy it, which makes getting a copy difficult and costly. However the version printed in the Monuments pour servir a l’histoire de l’Egypte…, t. IV, in 2 vols, was accessible and could be copied. The text is found on pp. 289-478; which means photocopying over 150 pages, one page at a time. However the format is Arabic at the top, French at the bottom, and there isn’t actually that much text on each page; less than in the Patrologia Orientalis editions.
I would have photocopied this, but a call on my mobile cut short my visit, to attend to family business. I’ll get a copy of this another day.
Wish it didn’t cost so much, tho.
