Aetius

Aetius c.396-454, Roman general. At first unfriendly to Valentinian III , he later made his peace with Valentinian's mother, Galla Placidia , and was given a command in Gaul. An ambitious general, he was embroiled in difficulties with his rival Boniface , who defeated him near Rimini in 432. Aetius went briefly into exile among the Huns but returned in 433 and rose to be the chief ruler of the Western Empire. He defeated the Germans in Gaul, then crowned his career by commanding (451) Roman and Visigothic troops in the repulse of Attila and the Huns in the battle near the modern Châlons-en-Champagne—a battle generally said to have saved the West. Valentinian, presumably jealous of Aetius' success, had him murdered.

Aetius (d. c.366), Arian sophist. He was a dialectician at Alexandria and was made a bishop by the Arians. He and his followers (Anomoeans) asserted that the Son, being begotten, was in essence unlike the Father, the Ingenerate. His Syntagmation is preserved by Epiphanius and in a few fragments elsewhere.

Aetius, Flavius (d. 454). Roman general. Gildas's work On the Ruin of Britain contains the passage known as The Groans of the Britons:
‘To Agitius thrice consul, the groans of the Britons…the barbarians push us back to the sea, the sea pushes us back to the barbarians.’ The Agitius of the text is usually identified as Flavius Aetius, consul for the third time in 446 and last effective Roman commander in Gaul.
