Priscus, an English writer, and, according to some authorities, bishop of London in the 5th century. He is proved by Holstenius to be the author of a treatise found in Augustine's works, volume 9, and published by Holstenius (Rome, 1663) under the title De Vita Christiana et Viduotate. Its precepts are good and practical, but Tillenont (Mem. 15:16) considers it as tending to Pelagianism, inasmuch as it reduces Christianity to love of God and our neighbors, including good works. It is given, with prolegomaena, in Galland, Bib. Vet. Patr. t. 9, and is reprinted in Migne, Patrol. Lat. 1:377 sq. — Clarke, Succession of Sac. Lit. 2:152; Cave, Hist. Lit. 1:401.
