Cú Chulainn
is an Irish warrior hero and demigod in the Ulster Cycle of Irish mythology, as well as in Scottish and Manx folklore. He is believed to be an incarnation of the Irish god Lugh, who is also his father. His mother is the mortal Deichtine, sister of king Conchobar mac Nessa.
Born Sétanta, he gained his better-known name as a child, after killing Culann's fierce guard dog in self defence and offering to take its place until a replacement could be reared, hence he became the "Hound (cú) of Culann".
