Camulus

In the ancient Celtic pantheon, Camulus or Camulos was a theonym for a god whom the Romans equated with Mars by interpretatio romana. He was an important god of early Britain and Gaul, especially among the Belgae and the Remi, a Gaulish tribe who lived in the area of modern Belgium. At Rindern, Germany, he was cited as Mars–Camulos on a stone with a corona of oak. Elsewhere he was portrayed with a ram-horned head. Evidence of his popularity can be seen in several place-names notably Camulodunum. Attempts to link him with the nursery character Old King Cole and Fionn's father Cumhall have been rejected by contemporary learned commentators
