What is "pseudo-ambrose"

Pseudo-Ambrose is the name given by Erasmus to refer to the author of a volume containing the first complete Latin commentary on the Pauline epistles. Alexander Souter has established that the same author wrote the Quaestiones Veteris et Novi Testament, which had long been attributed to Saint Augustine. Other works ascribed to the same author, less definitely, ore the Lex Dei sive Mosaicarum et Romanorum legum collatio, De bello judaico, and the fragmentary Contra Arianos sometimes ascribed to the pseudo-Hilary and the sermo 246 of pseudo-Augustine. They mention Simon Magus.

Internal evidence from the documents has been taken to suggest that the author was active in Rome during the period of Pope Damasus, and, almost certainly, a member of the clergy.
