Refutation of all Heresies

The Refutation of All HeresiesorPhilosophumena is a compendious Christian polemical work of the early third century, now generally attributed to Hippolytus of Rome. Most of it was recovered in 1842 in a manuscript at Mount Athos, but the complete text is not known. It catalogues both pagan beliefs and 33 gnostic Christian systems deemed heretical, making it a major source of information on contemporary opponents of Catholic orthodoxy.
