Terentius (comes et dux Armeniae)

Terentius was a Eastern Roman military commander whose recorded career flourished in the Caucasus region c. 369–374.

Terentius first appears as dux in undated tiles from Aquincum and Brigetio. He is next mentioned as comes and dux, being in command of the expedition that reinstated Pap as king of Armenia in 370. That same year, with 12 legions Terentius helped Sauromaces to reclaim the throne of Iberia from a Sasanian client. 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. In 375, Terentius appears retired and residing at Antioch. It is not clear whether Terentius is the same commander mentioned in 373 as attacking the Albanians and Iberians.

Terentius was a devoted Christian. 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. His daughters were nuns at Samosata.
