Does anybody know if Legio IV Flavia Felix served in Egypt in the late Third Century AD? I ask because one Trajanus Mucianus was designated ''Dux'' of this legion together with an unidentified II Legion probably around 275-85 - i.e. he commanded them both. Before his ''Dux'' posting Mucianus had been ''Praefectus (agens vice legatus?)'' of Legio II Trajana - which was almost certainly based in Alexandria after the Emperor Aurelian's defeat of Queen Zenobia of Palmyra. Could this legion have been the unidentified other unit in Mucianus's double command or was he posted from Egypt to the Balkans where IV Flavia was normally based to take command of that legion there together with some other II Legion - e.g. II Adiutrix?
