From Mogontiacum (Mainz), rationarius of the mag. militum Silvanus in Gaul in AD 355, mag. officiorum of Valentinianus I c. 365-371; in this period he covered up the machinations of his brother-in-law Romanus in Africa. This and the usurpation of the Moor Firmus [3] led to his dismissal. In 373, when his misdeeds were discovered, R. hanged himself.
