Vincentius the presbyter, a native of Gaul, practised in Divine Scripture and possessed of a style polished by speaking and by wide reading, wrote a Commentary On the Psalms. A part of this work, he read in my hearing, to a man of God, at Cannatae, promising at the same time, that if the Lord should spare his life and strength, he would treat the whole Psalter in the same way.
