The tendency of PhD theses to appear online is something we must welcome. One consequence is that we can sometimes find treasures. One of these is a thesis by Eugenia Constantinou, containing a detailed study of the Commentary on Revelation by the 6th century author Andrew of Caesarea (in Cappadocia). Studies, of course, are two a penny; but this one contains a translation of the text! I’m not yet clear what text was translated; the work appears in Migne’s Patrologia Graeca vol. 106.
Apparently this is one of the earliest patristic commentaries on this book of the bible in the Greek East, and it formed the basis for later commentators. You can find the PDF on the university website, here.
