A lengthy Gnostic apocalypse (132 pages of the manuscript) reported in the first person in the name of the prophet, Zostrianos, associated in antiquity with Zarathustra (Zoroaster). The title occurs at the end, to which is added: “Oracles of Truth of Zostrianos, God of truth, Teachings of Zoroaster.” Unfortunately, Codex VIII is very fragmentary, so much of the text is lost in lacunae. Zostrianos reports his ascent through the very levels of the universe and his encounter with various heavenly beings.

Lacking obvious influences, the text is heavily influenced by second- and early third-century Platonism. Zostrianos was one of the apocalypses read by members of Plotinus’ School in Rome in the mid-third century (VP 16). Extant only in Coptic, Zostrianos was originally in Greek, probably in the early third century, possibly in Egypt.
