PPO ORIENTISiRole name: PPO ORIENTIS 358-60: succeeded Musonianus as PPO Orientis in 358 Lib. Or. I 115-16, before Aug. 24 Lib. Ep. 21. He dismissed Nicentius 1 Lib. Ep. 21 and showed favour to Libanius Or. I 115-16 who praised his mild government Ep. 40, cf. Amm. XIX 12.6 (Hermogenes enim Ponticus ea tempestate praefectus praetorio ut lenioris ingenii sperne- batur (sc. by Constantius)). He is mentioned in Lib. Ep. 44, 49, 55, 95, 109, 127, 140, 173, 353, 970 (all a. 358/60). In office 359 May 28 CTh I 7.1^α. He received a letter from Basil of Ancyra Soz. IV 24.5. According to Amm. XXI 6.9 he died in office early in 361, but Lib. Ep. 138 (probably written in 360) says that Hermogenes had quarrelled with Libanius, but was reconciled after resigning his office, while his successor Helpidius 4 was in office by 360 Feb. 4 CTh XI 24.1. It seems therefore that Hermogenes resigned early in 360 and died early in 361.

He was interested in philosophical studies Lib. Ep. 21.

Possibly to be identified with Hermogenes 2 and Fl. Hermogenes 9.
