Ennodius calls Alico magnitudo vestra, nobilitas tua, and meus dominus which suggest that he must have been a high-ranking person, layman, and his name may suggest that he was of Gothic origin. See Amory 1997: 476; Heather 2007: 32n29.
We do not know when exactly the letter was written; his relationship to the presbyter Amantius suggests that it was still in the times when Ennodius was a deacon in Milan and not yet the bishop of Pavia.
