2d-century Italian Gnostic teacher. Almost nothing is known of his life. According to Clement of Alexandria (Strom. 4.71) and Hippolytus (Ref. 6.29, 35), he was, with Ptolemy, a leader of the Italian school of Valentinian Gnosis. He ranks as the first known commentator on the Fourth Gospel. Origen quotes some 48 passages of Heracleon's work in his own commentary on John, and Clement cites two other passages probably from the same work (ibid. and Eclogae 25.1). Largely on the basis of doctrinal similarities, H. C. Puech and G. Quispel have very plausibly assigned to Heracleon the Treatise on the Three Natures in the Jung Codex from the Chenoboskion manuscripts. At the core of Heracleon's system is the doctrine of the three natures and three classes of men: the material, associated with evil and the devil; the pneumatic, associated with the Father and the Pleroma; the psychic, associated with the Demiurge and capable of some purification by knowledge. The body of Jesus, the Italian Valentinians held, belonged to the psychic category.

Citation styles gives you the ability to cite reference entries and articles according to common styles from the Modern Language Association (MLA), The Chicago Manual of Style, and the American Psychological Association (APA).

Within the “Cite this article” tool, pick a style to see how all available information looks when formatted according to that style. Then, copy and paste the text into your bibliography or works cited list.

Because each style has its own formatting nuances that evolve over time and not all information is available for every reference entry or article, cannot guarantee each citation it generates. Therefore, it’s best to use citations as a starting point before checking the style against your school or publication’s requirements and the most-recent information available at these sites:
