BARNABAS, GOSPEL OF. We read in antiquity (e.g., in the Decretum Gelasii) of an apocryphal Gospel of Barnabas. (See APOCRYPHAL LITERATURE.) Traces of it may survive in a later book with this title, probably embodying materials partly Gnostic in character and origin (trans. by L. Ragg, Oxford, 1907) . It seems "a forgery of the 15th century at earliest, written in Italian by a renegade from Christianity to Islam" (M. R. James, The Apoc. N.T., p. xxvi.).
