Roman Sebasteion relief  sculpture of Leda and swan, Aphrodisias Museum, Aphrodisias, Turkey.   Against a white background.<br /> <br /> Zeus disguised as a swan assaults Spartan princess Leda. The bird stands on the tips of its outspread wings and presses its webbed foot on the thigh of modest, struggling Leda. The swan is supported from behind a small Eros. From this encounter came a large egg from which were born Helen and the Dionskouroi twins, Kastor and Polydeukes
