And Proetus and his Cyclopes built around Tiryns great walls of unhewn stone, which are standing to this day.
But there came a prophet to that hard-hearted Acrisius and prophesied against him, and said, 'Because you have risen up against your own blood, your own blood shall rise up against you; because you have sinned against your kindred, by your kindred you shall be punished.

Your daughter Danae shall bear a son, and by that son's hands you shall die.

So the Gods have ordained, and it will surely come to pass.' And at that Acrisius was very much afraid; but he did not mend his ways.
He had been cruel to his own family, and, instead of repenting and being kind to them, he went on to be more cruel than ever: for he shut up his fair daughter Danae in a cavern underground, lined with brass, that no one might come near her.

So he fancied himself more cunning than the Gods: but you will see presently whether he was able to escape them.
Now it came to pass that in time Danae bore a son; so beautiful a babe that any but King Acrisius would have had pity on it.

But he had no pity; for he took Danae and her babe down to the seashore, and put them into a great chest and thrust them out to sea, for the winds and the waves to carry them whithersoever they would.
The north-west wind blew freshly out of the blue mountains, and down the pleasant vale of Argos, and away and out to sea.
