Cycnus, the son of Sthenelus witnessed this marvel, who though he was kin to you Phaethon, through his mother, was closer still in love. Now, though he had ruled the people and great cities of Liguria, he left his kingdom, and filled Eridanus’s green banks and streams, and the woods the sisters had become part of, with his grief. As he did so his voice vanished and white feathers hid his hair, his long neck stretched out from his body, his reddened fingers became webbed, wings covered his sides, and a rounded beak his mouth. So Cycnus became a new kind of bird, the swan. But he had no faith in Jupiter and the heavens, remembering the lightning bolt the god in his severity had hurled. He looked for standing water, and open lakes hating fire, choosing to live in floods rather than flames.
