What does tiresias tell Odysseus to when he finally reaches home?

Odysseus did not see the spirit if Tiresias when he finally reached home. He saw it when he was in Italy. He foretells Odysseus's fate: that he will return home, reclaim his wife and palace from the wretched suitors, and then make another trip to a distant land to appease Poseidon. He warned Odysseus not to touch the flocks of the HeliOS, the son god, when he reaches the land of Thrinacia; otherwise, he won't return home without suffering much more hardship and losing all of his crew. He also told Odysseus that that Poseidon was punishing the Achaeans for blinding his son Polyphemus.
