Terentius was an Eastern Roman military commander whose recorded career flourished in the Caucasus region c. 369–374.
He is next mentioned as comes and dux, being in command of the expedition that reinstated Pap as king of Armenia in 370.
[1] In 373 or 374 Terentius urged the emperor Valens to replace Pap with a more amenable person in order to prevent Armenia from falling into Sasanian hands and, subsequently, lost Pap's confidence.
[2] It is not clear whether Terentius is the same commander mentioned in 373 as attacking the Albanians and Iberians.
When asked by Valens what reward he would choose for his services, Terentius requested—to the emperor's ire—that a church be given for the use of the orthodox Christians.
