King Acrisius himself was not ignorant that this might happen, and that his grandson might live to be the cause of his death. But the Greeks believed that if any man killed one of his own kinsfolk, he would be pursued and driven mad by the Furies called the Erinyes, terrible winged women with cruel claws. These winged women drove Orestes, the son of Agamemnon, fleeing like a madman through the world, because he slew his own mother, Clytaemnestra, to avenge his father, whom she and Ægisthus had slain. Nothing was so much dreaded as these Furies, and therefore Acrisius did not dare to slay his daughter and his grandson, Perseus, but only put them in the way of being drowned. He heard no more of them, and hoped that both of their bodies were rolling in the waves, or that their bones lay bleaching on some unknown shore. But he could not be certain--indeed, he soon knew better--and as long as he lived, he lived in fear that Perseus had escaped, and would come and slay him, as the prophetess had said in her song. The chest floated on the still waters, and the sea birds swooped down to look at it, and passed by, with one waft of their wings. The sun set, and Danae watched the stars, the Bear and Orion with his belt, and wrapped her boy up warm, and he slept sound, for he never knew fear, in his mother's arms. The Dawn came in her golden throne, and Danae saw around her the blue sharp crests of the mountains of the islands that lay scattered like water lilies on the seas of Greece. If only the current would drift her to an island, she thought, and prayed in her heart to the Gods of Good Help, Pallas Athênê, and Hermes of the Golden Wand. Soon she began to hope that the chest was drawing near an island. She turned her head in the opposite direction for a long while, and then looked forward again. She was much nearer the island, and could see the smoke going up from cottages among the trees. But she drifted on and drifted past the end of the isle, and on with the current, and so all day. A weary day she had, for the boy was full of play, and was like to capsize the chest. She gave him some wine and water, and presently he fell asleep, and Danae watched the sea and the distant isles till night came again. It was dark, with no moon, and the darker because the chest floated into the shadow of a mountain, and the current drew it near the shore. But Danae dared not hope again; men would not be abroad, she thought, in the night. As she lay thus helpless, she saw a light moving on the sea, and she cried as loud as she could cry. Then the light stopped, and a man's shout came to her over the water, and the light moved swiftly towards her. It came from a brazier set on a pole in a boat, and now Danae could see the bright sparks that shone in the drops from the oars, for the boat was being rowed towards her, as fast as two strong men could pull.
