After the defeat Syagrius in 486 at the Battle of Soissons, Aurelianus defected to the side of Clovis and aided him in the stabilisation of the domain.
[3] Known only by a cognomen common in Roman Gaul,[4] Aurelianus is mentioned in the Historia Francorum written by Gregory of Tours, although this may be another person of the same name.
According to the Liber historiæ and Fredegar, Clovis used Aurelianus as an intermediary to secretly arrange his marriage with Clotilde.
[9] The details of the secret meeting between Clotilde and Aurelianus, according to which he was disguised as a pilgrim, is more likely to be a myth than a historical fact.
He was present at the Battle of Tolbiac, where he advised Clovis to put his faith in the God of Clotilde and convert to Christianity.
[6] In the 19th century, Nicolas-Claude-Joseph Godelle suggested that the name of Arlaines, a hamlet of the commune of Ressons-le-Long where ruins were discovered in 1810, could come from an Aureliana villa, belonging to Aurelianus, making him a native of Soissons.
[12] In a book published in the 16th century, Nicole Gilles describes Aurelianus as the Grand Chamberlain of the king, but this anachronism is corrected in 1623 by Pierre Bardin.
