Arethusa, yet another huntress who loved the comfort of the deep woods. She detested love and marriage and vowed never to marry.
One day, as she was tired and hot from the chase, she came upon a crystal-clear river deeply shaded in silvery willows. She undressed and bathed in the river, which was a place that was perfect for bathing. For a while, she swam to and fro, until she began to feel something below her. She sprang up from the river and stood on the bank, as she heard a voice that said "Why such haste fairest maiden?" Without looking back she fled in terror. With all the speed that she could muster up, she kept running and running, but still she was pursued by one stranger, he told her he was the god of the river, Alpheus, and that he was following her only out of absolute love. But she wanted no part of him and yet he unsparingly followed. Arethusa called to her god, Artemis, she changed her into a spring of water, and split the earth so a tunnel was made under the sea from Greece to Sicily. Arethusa plunged down and emerged in Ortygia, where the place in which her spring bubbles up is holy ground, sacred to Artemis.
But it is said that she is still not free of Alpheus. The story is that the god changed back into a river, followed her through the tunnel and the now his water mingles with hers in the fountain. They say that often Greek flowers are seen coming up from the bottom, and that if a wooden cup is thrown into the Alpheus in Greece, it would reappear in Arethusa's well in Sicily.
