Legendary warrior of Celtic mythology who appears in many stories.
In "Bricriu's Feast" in the Ulster cycle , he is one of three knights challenged by a giant to let him chop their heads off after they behead him; of the three, only Cú Chulainn keeps the bargain. Conall Cernach is probably related to Cernunnos , and their names may be cognates. See also Gawain .
