The Gospel of Basilides is a "lost" text from the New Testament apocrypha by Basilides, mentioned by Origen,[1] Jerome, Ambrose,[2] Philip of Side, and the Venerable Bede.[3] It was composed in Egypt around 120 to 140 AD. In all likelihood, this gospel was compiled of canonical gospels, the text being shortened and altered to suit Basilides's Gnostic tenets, a diatessaron. or harmony, on Gnostic (Docetic) lines.[4]
