In
early Christian heresiology, the
Panarion (Greek: Πανάριον, "Medicine Chest"), to which 16th-century
Latin translations gave the name
Adversus Haereses (Latin: "Against Heresies"), is the most important of the works of
Epiphanius of Salamis (d. 403). It was written in
Koine Greek beginning in 374 or 375, and issued about 3 years later, as a treatise on
heresies, with its title referring to the text as a "stock of remedies to offset the poisons of heresy." It treats 80 religious
sects, either organized groups or philosophies, from the time of
Adam to the latter part of the 4th century, detailing their histories, and rebutting their beliefs. The Panarion is an important source of information on the
Jewish Gospels, the
Gospel of the Ebionites, and the
Gospel of the Hebrews.
