Question: how cuchulainn got his name?
Answer: When Setanta got there the Culenn's hound attacked him. Setanta hit the ball at the hound with his hurley and it went right down the dog's throat and he was dead. ... Setanta said to Culann “Since your hund is dead I will guard your house now” so he was called Cuchulainn which means the hound of Culann”.
