In 396, Ambrose of Milan sent Victricius (as well as Paulinus of Nola and others) some relics of Vitalis and Agricola.

[2] Victricius wrote a sermon, De Laude Sanctorum (On the Praise of the Saints), celebrating the arrival of the relics from Italy.

[3] He mentions that he had been away from Rouen (396), as he had been requested to travel to Britain to help resolve some doctrinal issues.

Victricius describes Britain as a wild and hostile place dealing with paganism and heresy in contrast with Italy with its abundance of holy sites and relics of martyrs.

[1] Victricius welcomes the arriving relics and names the (relics of) saints who are already present in Rouen: John the Baptist, Andrew, Thomas, Gervasius and Protasius, Agricola, and Euphemia.
