Odysseus rested and Tiresias warned him of the trouble ahead. He told him not to kill the cattle of the sun and he foresaw that he will return home alone. After he deals with the suitors in Ithaca, he is to walk inland until he finds people who have never heard of the sea and sacrifice to Poseidon. Odysseus asked him why his mother did not look at him and Tiresias said that she must be allowed to taste the blood.
