(feast day Apr 18). At the end of Eusebius's brief account of the martyrdom of Apollonius, “a man who stood in high esteem among the faithful of that time on account of his culture and erudition” (Hist. eccl. V 21.2–5), he refers to a text that he had “in his collection of the early acts of the martyrs.” These acts may be identical with the so-called Acts of Apollonius, a largely apologetic work surviving in Greek and Armenian; its literary quality and fictional style led Jerome (Vir. ill. 42) to identify Apollonius as a Roman senator.
