Twelve smaller idols, these of stone, formed a ring around the Crom Cruach. The golden idol represented a god, though we do not know which one. On the holiday of Samhain, the Irish were said to sacrifice one third of their newborns to him, in order to insure good weather, good yields of milk and corn, and the fertility of their cattle and crops. The Irish feared this god greatly, and it was dangerous to worship him, as many died in the process.

St. Patrick, who is the patron saint of Ireland, destroyed the idol and sent it back into the earth. He instructed the people to not burn their cows or children.

He was killed in battle after failing to recognize Morrigan, the battle goddess. She forced him to break one of his geasa and caused his death. Two of his geasa stated that he always had to eat food being prepared at a roadside, and that he could not eat dog meat. The last one is probably because of his name, making eating meat of a dog similar to cannibalism for him. Morrigan appeared as a hag and prepared dog meat as he passed her on the road.
