Give me an analysis of what this quote means: '"Hear me, Poseidon who circle the earth, dark-haired. If truly I am your son, and you acknowledge yourself as my father, grant that Odysseus, sacker of cities, son of Laertes, who makes his home in Ithaca, may never reach that home; but if it is decided that he shall see his own people, and come home to his strong-founded house and to his own country, let him come late, in bad case, with the loss of all his companions, in someone else's ship, and find troubles in his household."
