Domitian (Latin: Domitianus, Greek: Δομιτιανός; c. 550 – 602) was the nephew of the Roman emperor Maurice and the archbishop of Melitene in Roman Armenia from around 580 until his death.[1] He was renowned as a diplomat and is regarded as a saint by the Chalcedonian churches for enforcing orthodoxy in the northeast of the empire.[2] He unsuccessfully tried to convert the Persian king Khosrow II to Christianity when he helped restore him to his throne in 590–591. In the monophysite tradition, however, he is remembered for his brutal persecutions.[3]
