A fourth-century bishop cataloged eighty heresies, comparing his theological rivals to poisonous beasts.

In short: Epiphanius of Salamis was a relentless defender of orthodoxy who authored the Panarion, a massive handbook designed to cure the faithful of heretical ideas. By mapping diverse philosophical and religious systems as dangerous infections, he created a unique, albeit aggressive, taxonomy of belief that remains a vital historical record.

Born around 310–320 in the settlement of Besanduk, Epiphanius became a prominent figure in the late fourth-century Church. After living as a monk in Egypt, he founded a monastery at Ad in Roman Palestine, where he gained a reputation for linguistic mastery, earning the nickname Pentaglossos for his fluency in five languages. In 365 or 367, he was consecrated Bishop of Salamis, Cyprus, a position he held for nearly forty years until his death in 403.

His most famous work, the Panarion, written between 374 and 377, serves as an encyclopedic refutation of eighty heresies. Epiphanius organized these into a complex framework, beginning with four 'mothers' of pre-Christian thought—barbarism, Scythism, Hellenism, and Judaism—before detailing various philosophical schools and Christian sects. A distinctive feature of this work is his use of zoological metaphors; he described his opponents as specific animals, such as comparing Origen to a noisy toad or the Gnostics to fanged snakes, detailing how to protect oneself from their metaphorical poison.

Epiphanius was also a fierce opponent of religious imagery, famously tearing down a curtain depicting a saint in a church at Anablatha. This act, documented in a letter to John, Bishop of Jerusalem, became a flashpoint in later ecclesiastical disputes. While his zeal sometimes led him to rely on hearsay, his writings provide rare access to lost works and early Jewish gospels. Though his later influence was bolstered by false attributions—such as the Physiologus, a source for medieval bestiaries—his genuine contributions to metrology and historical theology remain significant for understanding the complex religious landscape of late antiquity.
