Satiated Siren by Gustav-Adolf Mossa, 1905. In some versions of the myth, the sirens were once nymphs and companions of the goddess Persephone. When Persephone was abducted by Hades the nymphs prayed for wings so that they could search for their lost friend. Their wish was granted and they became half bird and half woman. Another version (Ovid V, 551)) states that as punishment for not intervening when Persephone was abducted, Demeter changed their form.
