The subject of this paper is a celebrated incident in Constantius' Life of St. Germanus. The work is a near contemporary piece, evidently drawing on eye witness accounts. It was composed in Gaul about 480 A.D. 1 Constantius provides several interesting and possibly historical details concerning conditions in Britain during the transition from Celtic independence to Saxon dominance. St. Germanus visited Britain in 429 to combat the Pelagian heresy. 2 While there, according to Constantius, he led the Britons in a military victory over invading Picts and Saxons, the Alleluja Victory. He thereafter passed into a prominent position in British legend and history. 3
