The Gospel of Thomas, an account of the Childhood of Jesus, is extant in three forms, two in Greek and one in Latin:  these are all translated in Clark’s Ante-Nicene Library.  The work is wrongly attributed by Cyril to a disciple of Manes, being mentioned long before Hippolytus (Refutation of all Heresies, V. 2) and by Origen (Hom. I. in Lucam):  “There is extant also the Gospel according to Thomas.”
