Now on a day a mysterious thing happened; the old poet Pindar, who lived long after, in the time of the war between the Greeks and the King of Persia, says that a living stream of gold flowed down from the sky and filled the chamber of Danae. Some time after this Danae bore a baby, a son, the strongest and most beautiful of children. She and her nurse kept it secret, and the child was brought up in an inner chamber of the house of bronze. It was difficult to prevent so lively a child from making a noise in his play, and one day, when Acrisius was with Danae, the boy, now three or four years old, escaped from his nurse, and ran from her room, laughing and shouting. Acrisius rushed out, and saw the nurse catch the child, and throw her mantle over him. Acrisius seized the boy, who stood firm on his little legs, with his head high, frowning at his grandfather, and gazing in anger out of his large blue eyes. Acrisius saw that this child would be dangerous when he became a man, and in great anger he bade his guards take the nurse out, and strangle her with a rope, while Danae knelt weeping at his feet. When they were alone he said to Danae: 'Who is the father of this child?' but she, with her boy on her arm, slipped past Acrisius, and out of the open door, and up the staircase, into the open air. She ran to the altar of Zeus, which was built in the court, and threw her arms round it, thinking that there no man dared to touch her. 'I cry to Zeus that is throned in the highest, the Lord of Thunder,' she said: 'for he and no other is the father of my boy, even Perseus.' The sky was bright and blue without a cloud, and Danae cried in vain. There came no flash of lightning nor roll of thunder. 'Is it even so?' said Acrisius, 'then let Zeus guard his own.' He bade his men drag Danae from the altar; and lock her again in the house of bronze; while he had a great strong chest made. In that chest he had the cruelty to place Danae and her boy, and he sent them out to sea in a ship, the sailors having orders to let the chest down into the waters when they were far from shore. They dared not disobey, but they put food and a skin of wine, and two skins of water in the chest, and lowered it into the sea, which was perfectly calm and still. It was their hope that some ship would come sailing by, perhaps a ship of Phoenician merchant-men, who would certainly save Danae and the child, if only that they might sell them for slaves.
