Gnostic Texts of Nag Hammadi
Nag Hammadi, a village in Upper Egypt, is best known for being the site where in December 1945, thirteen leather-bound papyrus codices from the 3rd and 4th centuries A.D. buried in a sealed jar were found by a local farmer, Mohammed Ali Samman. The writings in these codices comprised 52 mostly Gnostic tractates (treatises).
The contents of the codices were written in Coptic, though the works were probably all translations from Greek. Most famous of these works must be the Gospel of Thomas, of which the Nag Hammadi codices contain the only complete copy.
Gospel of Thomas (Non-canonical, New Testament Apocrypha)
Gospel of Mary (Non-canonical, New Testament Apocrypha)
N.B.: The Gospel of Mary Magdalene was found in the Akhmim Codex, a Gnostic text of the New Testament apocrypha acquired by Dr. Rheinhardt in Cairo in 1896. However, it was not published until 1955, after the Nag Hammadi libarary had also appeared. The other texts of the Akhmim Codex were in the Nag Hammadi texts, but not this Gospel.
