There is supposed to be a new edition of the Armenian text of Eusebius’ Chronicle, to appear in the Berlin GCS series. Richard Burgess communicated this information to the LT-ANTIQ list a year or two back. If so, this would alter matters again, as a printed Classical Armenian (=’Grabar’) text could be scanned. I am told that the support for Grabar in Abbyy Finereader 8.0 Pro (which I have) is very good, thereby avoiding the need to get Aucher retyped. Perhaps the right choice is to defer dealing with the Armenian, and to proceed with the Latin and German.
