The Chaldaean Oracles have survived as fragmentary texts from the 2nd century AD, and consist mainly of Hellenistic commentary on a single mystery-poem that was believed to have originated in Chaldea (Babylonia). They appear to be a syncretic combination of Neoplatonic elements with Persian or Babylonian ideas. Zoroaster's authorship is traditional, and not generally accepted by scholars.
