Hegemonius

The AA can be dated to the first half of the fourth century, since some of its content is made use of by Cyril of Jerusalem (Catecheses 6.20–35) writing around 350 CE. It was not known to Eusebius two decades earlier, although that does not rule out an earlier composition. Hegemonius makes the telling blunder of having Archelaus refer to “more than three hundred years” between Christ and Mani (AA 31.7), inadvertently placing his characters in his own temporal locale in the second quarter of the fourth century. We have no other information on who Hegemonius was, or when or where he lived.
