Bruce Codex
The Bruce Codex (Latin: Codex Brucianus) is a Coptic codex that contains rare Gnostic works; the Bruce Codex is the only known surviving copy of the Books of Jeu and another work simply called Untitled Text or the Untitled Apocalypse. In 1769, James Bruce purchased the codex in Upper Egypt. It is currently kept in the Bodleian Library in Oxford (Bruce 96), where it has been since 1848.
