I went to Cambridge today to take a look at Roger Cowley, Ethiopian biblical interpretation, Cambridge 1989. There is supposed to be a reference to a possible Ethiopic version of some of the Eusebius, Gospel Problems and Solutions material. Unfortunately I was quite unable to find it. I’ll have to order up the book by ILL and look then.
Another update has come through on the Origen book. With luck the main bulk of the work will be done by Friday, I am advised. That will be very good news.
