In Celtic mythology, Belatu-Cadros, or Belatucadros ("fair shining one" or "the fair slayer"), was a deity worshipped in northern Britain, particularly in Cumberland and Westmoreland. He may be related to Belenus, and was equated in the Roman period with Mars. Sometimes referenced as Cernunnos. He appears to have been worshipped by lower-ranked Roman soldiers as well as by Britons.
