The figure of this lamp is sometimes, and incorrectly, described as a duck; given the shape of its beak and the length of its neck, it is actually a swan. Two small children, one on either side, are folded within the bird's wing. Of each child, only the head and one arm are visible. The lamp depicts Castor and Pollux (or perhaps, Helen and Pollux), whose father, Zeus, took the form of a swan to impregnate their mother Leda.
