 This is the first Latin commentary on Matthew to have survived in its entirety.Hilary's commentary was strongly influenced by Tertullian and Cyprian, and made use of several classical writers, including Cicero, Quintilian, Pliny and the Roman historians.Hilary's expositions of the Psalms, "Tractatus super Psalmos", largely follow Origen, and were composed some time after Hilary returned from exile in 360.
