Cernunnos is the mysterious horned deity worshipped by Iron age Celts across Europe until the end of the first century. Very little is known about Cernunnos except his name and his image, which appears on numerous stonecarvings and other artifacts throughout Europe. He appears crowned with stag's antlers, is often seated in a meditative position, and is almost always depicted with images of wild animals.
His Celtic name is unknown, although he may be associated with Derg Corra, the early Celtic "Man in the Tree." Cernunnos is a Roman name meaning "horned one." He is often associated with Herne the hunter, a character of British folk myth, and the "Green man" of European architecture. Roman invaders associated Cernunnos with the god Mercury. He is later associated with "Herne the hunter," of European legend, and his appearance was eventually adapted as the Christian Devil's.
The image which appears above is from the "Gundestrup Cauldron," a ritual object of unknown use discovered in pieces in a peat bog in Denmark.
