When Theodosius, the son of the general whose victories have been named, became joint Emperor with Gratian, his elevation to power excited the anger of Maximus, a former fellow - officer, who was proclaimed Emperor, it is said at York. He raised an army, which included the flower of the British youth, invaded Gaul and defeated Gratian, who was killed A.D. 383.  But the star of Maximus soon paled, and he was defeated and slain by Theodosius A.D. 388. The victor died in 395, and in his reign was appointed the last known Governor of Britain, Chrysanthus, who was Vicarius.(7)
