Excerpta ex Theodoto 63, as recorded by Clement of Alexandria. Several gnostic texts found at Nag Hammadi also emphasize the ogdoad (as the eighth day or eighth heaven); see, for example, Gospel of the Egyptians 41, 58; Paraphrase of Shem 46; Testimony of Truth 55; Zostrianos 6; Origin of the World 102–104; Apocalypse of Paul 23–24. These texts are translated in James Robinson, ed., The Nag Hammadi Library in English (New York: Harper & Row, 1977, and later editions).
