Dioscorus Boles has translated from Arabic into English a hitherto unpublished passage in ‘Abu Salih’ (actually the Coptic writer, Abu’l Makarem) which deals with the plight of the defeated ordinary crusaders in Egypt after the failure of the Second Crusade. It’s here, in the comments on a post on Michael the Syrian which turned into a discussion of Abu Salih.
I recommend it highly, and I hope that Dioscorus will give us more of this writer.
