Cernunnos is the conventional name given in Celtic studies to depictions of the "horned god" of Celtic polytheism. Over 50 examples of his imagery have been found from the Gallo-Roman period, mostly in north-eastern Gaul as well as among the Celtiberians. Cernunnos is depicted with antlers, seated cross-legged, and is associated with stags, horned serpents, dogs, bulls, and rats. He is usually holding or wearing a torc.
Interpretations of his role vary from seeing him as a god of animals, nature and fertility to a god of travel, commerce and bi-directionality. ~ From Wikipedia
