 Sethianism attributed its "gnosis" to Seth, third son of Adam and Eve and "Norea", wife of Noah, who also plays a role in Mandeanism and Manicheanism.Their main text is the "Apocryphon of John", which does not contain Christian elements, and is an amalgam of two earlier myths.Earlier texts such as Apocalypse of Adam show signs of being pre-Christian and focus on the Seth, third son of Adam and Eve.
