The Hexæmeron of Ambrose is rather an imitation than a translation or adaptation of that of Basil.  Basil’s Hexæmeron was translated into Latin by Eustathius Afer (c. A.D. 440) and is said to have been also translated by Dionysius Exiguus, the Scythian monk of the 6th C. to whom is due our custom of dating from the Saviour’s birth.
