Agitius

Ætius

Historically, a steward of Gaul under the Roman emperor Valentinian in the second quarter of the fifth century.

According to the Arthurian chronicles, the Britons entreated him for assistance when, after the Roman withdrawal, Britain was invaded by Picts and Scots. Beset by martial problems at home, Ætius refused to send aid.

The Britons took their plea to King Aldroen of Brittany, who sent them his brother, Arthur’s grandfather, Constantine.
