The Untitled Text[1][2] in the Bruce Codex—also called the Untitled Treatise,[3] the Untitled Apocalypse,[4] and The Gnosis of the Light[4]—is a Gnostic text. When James Bruce acquired the codex in Egypt in 1769,[5] "very little knowledge" was available about this period of Gnostic Christianity.[4] It was one of the few known surviving Gnostic works until the discovery of the Nag Hammadi library in 1945.[6] Carl Schmidt described the text's author as having "full knowledge of Greek philosophy" and being "full of the doctrine of the Platonic ideas."[4]
