(Flavius) Hermogenes (Greek: Έρμογένης; c. 300 – 361) was a Roman senator who served in various civilian offices from the reign of Licinius through to Constantius II.
[1]: 424 When he reached the age of manhood, Hermogenes left Licinius’ court and began intensively studying philosophy, as well as becoming proficient in both Latin and Greek.
Returning to the imperial court at Constantinople under Constantine I, Hermogenes was probably appointed magister of one of the sacra scrinia (or perhaps Quaestor sacri palatii).
[1]: 425 In this role, he encouraged benevolent legislation, helped people in danger, secured the appointment of decent men as governor, and provided assistance to petitioners before the court.
[1]: 425 Hermogenes was next noted to be serving near the Danube, and this was followed by his appointment as proconsular governor of Achaea, with a rank of vir clarissimus, which he probably held during the reign of Constantius II, sometime between 350 and 358.
