Note 130 — LETTERS
Charles Lett Feltoe translation
No doubt Macrianus is meant, who is mentioned further on, but it is difficult to account for the exact epithets which Dionysius here applies to him. Apparently he had been Valerian’s tutor in some kind of magic, and had allied himself somehow with the Jewish colony in Alexandria (hence ἀρχισυνάγωγος), who would, of course, be hostile to the Christians.
