Ambrosiaster

Ambrosiaster is the name given to the writer of a commentary on St Paul's epistles, "brief in words but weighty in matter," and valuable for the criticism of the Latin text of the New Testament. The commentary itself was written during the papacy of Pope Damasus I, that is, between 366 and 384, and is considered an important document of the Latin text of Paul before the Vulgate of Jerome, and of the interpretation of Paul prior to Augustine of Hippo.
