Zostrianos

Zostrianos is a Sethian Gnostic text. It is the first tractate of two in Codex VIII of the Nag Hammadi library. It takes up 132 of the 140 pages in the codex, making Zostrianos the longest tractate of the entire library. However the text is extensively damaged, especially in the center, making the document difficult to fully understand. The Coptic manuscript is a translation of a Greek original, likely written in Alexandria in c. 200 AD. In the text, Zostrianos goes on a heavenly journey and receives divine knowledge from the aeons.

The work is likely the same Zostrianos that Porphyry criticized in Life of Plotinus. Like other Sethian Gnostic texts Marsanes, Allogenes, and Three Steles of Seth, its ideas appear more Middle Platonic or Neoplatonic than Christian. However, Porphyry said that these works belonged to Christian heretics. Bentley Layton explains this apparent contradiction with the belief that Zostrianos was written by a Gnostic Christian author who was fascinated with Eastern religious heroes who had special knowledge relating to the divine, such as Zoroaster.
