Pick, Bernhard. "Chapter Seven: The Gospel of Eve." Paralipomena: Remains of Gospels and Sayings of Christ. Chicago: Open Court Publishing Company, 1908, 29-30.
The "Gospel of Eve" comes from the Ophites, a group descended from Valentinianism. Two passages are preserved by Epiphanius (Pick 1908, 29). In the first, the figure we must assume is either Satan or Christ appears with Even, describing how he is she and that he plants himself and her as seed which will be plucked up. In the second, there is a description of the twelve seasons and fruits of the tree of life, recast as a symbol of menstruation (Pick 1908, 30).
