Rumoridus was of Germanic origin, and had not converted to Christianity. Ambrose, bishop of Milan, described Rumoridus in a letter to Eugenius as maintaining the practice of ethnic religions from earliest childhood. He began his service as a career military officer, and may have been posted at some point in the Diocese of Thrace. He was eventually appointed a magister militum under Valentinian II in AD 384, during which time he gave his support for the restoration of the Altar of Victory in the Curia Julia.
Although he was probably an old man, in AD 403 Rumoridus was made consul posterior in the West alongside the infant Theodosius II in the East. It has been suggested by Martindale and Jones that he was recalled to military service as a result of the crisis precipitated by the invasion of Italy by Alaric and the Visigoths in AD 402, and may have played a part in Alaric’s defeat and retreat from Italy in AD 403. His consulship is recorded in several inscriptions, with considerable variety in the spelling of his name.
