About Mallius Theodorus

Born 350. Mallius Theodorus was a Roman writer, politician and grammarian.

Flavius Mallius Theodorus ( c. 376–409) was a Roman politician and author of an extant treatise on metres, De metris, one of the best of its kind (H. Keil, Grammatici Latini, vi.). He also studied philosophy, astronomy and geometry, and wrote works on those subjects, which, together with his consulship, formed the subject of a panegyric by Claudian.

Biography

Theodorus' life is known in detail thanks to Claudian's panegyric, Panegyricus dictus Manlio Theodoro consuli.

He came from a family of humble origin, which, nonetheless, allowed him to start an administrative career. Claudian says that Theodorus was member of the court of a Praetorian prefect, as lawyer; historians think this was probably the Praetorian prefect of Italy, and that this office should be dated to 376. He was then governor of an African province, probably around 377, (c. 378). with an office that historians identify as magister memoriae and date to 379, or, more probably, of comes rerum privatarum; He then became Praetorian prefect of Gaul, an office held in c. 382, and from 397 to 399 held the post of Praetorian prefect of Illyricum, Italy and Africa (several laws conserved in the Codex Theodosianus were addressed to him in this period). a powerful and hated high officer of the Eastern court, who was killed that same year.

Augustine and Theodorus

Augustine of Hippo knew Theodorus. When he converted to Christianity, Augustine wrote a book, On blessed life, which he dedicated to Theodorus. Theodorus, who at the time had retired from the court, was one of the Christian platonic intellectuals that Augustine met in Milan.

When, in 397, he wrote the Confessions, Augustine had changed his mind on Theodorus, who now was Praetorian prefect of Italy: Augustine described Theodorus as "a man inflated with monstrous pride" and despised his own admiration of him years before.
