Paulinus was Amandus' catechumen .
Paulinus pleads the case of Basilius in several letters to both Bishop Delphinus and Presbyter Amandus of Bordeaux (letters 12, 14, and 15).

For unknown reasons, Presbyter Basilius was expelled from the house in which he lived and which supposedly belonged to Daducius. See  and .
Portus Alingonis was located not far from Bordeaux. Delphinus was at that time engaged in building a church there (see Paulinus of Nola, Letter 20.3).
The dating of this letter is based on analysis of other letters sent by Paulinus to Amandus and Delphinus of Bordeaux (Walsh 1966: 1.234-235).
