A War God Known Mostly from Stone

Camulus is a Gaulish and British war god whom the Romans identified with their own Mars, worshipping him under the combined name Mars Camulus. He is a good example of a Celtic deity known almost entirely from the archaeological and epigraphic record rather than from any body of myth: no stories about him survive, and what we know comes from inscriptions and place-names left across the Roman-period Celtic world. Those traces show that his cult was genuinely widespread, dedications to him have been found in Gaul, in Roman Britain, and in the Rhineland, set up by soldiers and others across the north-western provinces of the empire. His name is preserved most durably in a great city: Camulodunum, the fortress of Camulus, was the Roman name of what is now Colchester in England, the earliest Roman capital of Britain, so that a war god otherwise lost to us is remembered in the name of a town.

The equation with Mars tells us that the Romans, who habitually matched foreign gods to their own, recognised in Camulus a deity of war and martial power; the many dedications by military men point the same way. Beyond that, honesty requires acknowledging how little is known: Camulus belongs to the large class of Celtic gods whose worship is attested but whose character and stories have not come down to us, glimpsed only through the Roman lens that renamed him and the stone that recorded his name.
