Cernunnos at English => English (The Britannica Concise) Of Explained:
In Celtic religion, a deity worshiped as "lord of wild things." He wore stag antlers and sometimes carried a torque (sacred neck ornament). He was worshiped primarily in Britain, but there are also traces of his cult in Ireland. He is probably the source for the horned god that appears in Christian medieval manuscripts as a symbol of the Antichrist.
