Which Celtic god is often depicted with antlers and a torc?

The Celtic god often depicted with antlers and a torc is Cernunnos. His name is clearly attested on the first-century CE Pillar of the Boatmen from Paris, beside an image of an antlered figure associated with torcs.

Cernunnos is usually shown as an aged or bearded man, sometimes seated cross-legged, with deer antlers. He may hold or wear a torc, a valuable neck-ring that was an important symbol in Celtic art, and is often accompanied by animals or a ram-horned serpent.

The imagery has led scholars to connect him with wild animals, fertility, abundance, and possibly the underworld, but the evidence does not provide a single securely defined ancient theology. The name is also applied by modern scholars to a broader group of similar antlered images found across parts of Gaul and beyond.

Cernunnos should not be confused with Esus, Teutates, or Taranis. Those names belong to other Gaulish deities, whereas the antlers-and-torc combination is the signature visual clue associated with Cernunnos.
