The Gospel of Judas, recently reconstructed in spring of 2006, is a Gnostic (Specifically Cainite) and heretical account of the ApostleJudas Iscariot, and his supposed secret conversations with Jesus. It probably was written some time around 130-170 A.D., making it impossible for Judas to have written it, and is typical of many Gnostic gospels or works in it's interpretation by the gnostics as containing "hidden knowledge" of some sort, specifically in it's beginning, "The secret account of the revelation that Jesus spoke in conversation with Judas Iscariot." The earliest extant manuscripts seem to date from the 4th to 5th century.
