Eusebius, a native of Sardinia, at first a lector at Rome and afterwards bishop of Vercelli, sent by the emperor Constantius to Scythopolis, and afterwards to Cappadocia, on account of his confession of the faith, returned to the church under the emperor Julian and published the Commentaries of Eusebius of Cæsarea on the Psalms, which he had translated from Greek into Latin, and died during the reign of Valentian and Valens.
