Meanwhile the chiefs carefully cleansed the old man's squalid skin and with due selection sacrificed sheep which they had borne away from the spoil of Amycus. And when they had laid a huge supper in the hall, they sat down and feasted, and with them feasted Phineus ravenously, delighting his soul, as in a dream. And there, when they had taken their fill of food and drink, they kept awake all night waiting for the sons of Boreas. And the aged sire himself sat in the midst, near the hearth, telling of the end of their voyage and the completion of their journey: "Listen then. Not everything is it lawful for you to know clearly; but whatever is heaven's will, I will not hide. I was infatuated aforetime, when in my folly I declared the will of Zeus in order and to the end. For he himself wishes to deliver to men the utterances of the prophetic art incomplete, in order that they may still have some need to know the will of heaven. "First of all, after leaving me, ye will see the twin Cyanean rocks where the two seas meet. No one, I ween, has won his escape between them. For they are not firmly fixed with roots beneath, but constantly clash against one another to one point, and above a huge mass of salt water rises in a crest, boiling up, and loudly dashes upon the hard beach. Wherefore now obey my counsel, if indeed with prudent mind and reverencing the blessed gods ye pursue your way; and perish not foolishly by a self-sought death, or rush on following the guidance of youth. First entrust the attempt to a dove when ye have sent her forth from the ship. And if she escapes safe with her wings between the rocks to the open sea, then no more do ye refrain from the path, but grip your oars well in your hands and cleave the sea's narrow strait, for the light of safety will be not so much in prayer as in strength of hands. Wherefore let all else go and labour boldly with might and main, but ere then implore the gods as ye will, I forbid you not. But if she flies onward and perishes midway, then do ye turn back; for it is better to yield to the immortals. For ye could not escape an evil doom from the rocks, not even if Argo were of iron.
