Cúchulainn

Means "hound of Culann" in Irish. This was the usual name of the warrior hero who was named Sétanta at birth, given to him because he took the place of one of Culann's hounds after he accidentally killed it. The Ulster Cycle of Irish mythology tells of Cúchulainn's many adventures, including his single-handed defence of Ulster against the army of Queen Medb.
