The stories involved may have dated from the second century, but they survive only in a few late Greek manuscripts and in Arabic and Armenian versions, not all of which give the same material. The work probably has no relationship to the Coptic Gospel of Thomas found at Nag Hammadi. See Edgar Hennecke, New Testament Apocrypha, Vol. 1: Gospels and Related Writings, ed. Wilhelm Schneemelcher; transl. R.McL. Wilson (Philadelphia: Westminster, 1963), pp. 392–401. For material on all of the so-called infancy gospels, see pp. 363–417.
