De Viris Illustribus (Illustrious Men)

Hilary, a bishop of Poitiers in Aquitania, was a member of the party of Saturninus bishop of Arles. Banished into Phrygia by the Synod of Beziérs he composed twelve books Against the Arians and another book On Councils written to the Gallican bishops, and Commentaries on the Psalms that is on the first and second, from the fifty-first to the sixty-second, and from the one hundred and eighteenth to the end of the book. In this work he imitated Origen, but added also some original matter.

There is a little book of his To Constantius which he presented to the emperor while he was living in Constantinople, and another On Constantius which he wrote after his death and a book Against Valens and Ursacius, containing a history of the Ariminian and Selucian Councils and To Sallust the prefect or Against Dioscurus, also a book of Hymns and mysteries, a commentary On Matthew and treatises On Job, which he translated freely from the Greek of Origen, and another elegant little work Against Auxentius and Epistles to different persons. They say he has written On the Song of Songs but this work is not known to us. He died at Poictiers during the reign of Valentinianus and Valens.
