Marius Valerianus

Marius Valerianus was a governor of Britannia Inferior, a province of Roman Britain between 221 and 223. He is known through three inscriptions he left at Chesters, Netherby and South Shields. These inscriptions  illustrate the fact that the praetorian governor of the Lower province was responsible for the whole of the northern frontier of Roman Britain, from the North Sea to the western outpost north of Carlisle.

He may be the same man attested as a centurion in the Praetorian Guard, at some point not earlier than the reign of Septimus Severus.
