Culann
In the Ulster Cycle of Irish mythology, Culann was a smith whose house was protected by a ferocious watchdog.
He invited Conchobar mac Nessa, king of Ulster, and his retinue to a feast at his house. On the way Conchobar saw his young nephew Sétanta playing hurling, and was so impressed he invited the boy to join him at the feast. Sétanta told him he would catch him up once the game was over.
