Chauncey Bradley Ives American (1810-1894) Undine Rising from the Waters, modeled ca. 1880-1882 . An undine is a legendary figure, a mortal sea sprite that lacks a soul. She must assume human form and trick a man into marriage in order to gain a soul, and with it, immortality. Once wed, she can leave the sea, but only as long as her husband remains true. If her deception is discovered and her mate deserts her, the undine must destroy him. Ives chose the moment that this undine rises out of the water, and reaching sensuously heavenward to receive her soul.
