From the "Four Seasons" mosaic. The mosaic, inv. 1018, is from Harbiye, from the second century A.D. It's named after the winged figures representing the seasons. This is Paris and Helen (between Autumn and Winter). Paris is standing in front of a tree. Helen is standing with a leaf in her hand. Aphrodite is standing behind Helen.
Enc. Britt.: The “judgment of Paris” was and continues to be a popular theme in art. According to legend, Paris was chosen by Zeus to determine which of three goddesses was the most beautiful. Rejecting bribes of kingly power from Hera and military might from Athena, he chose Aphrodite and accepted her bribe to help him win the most beautiful woman alive. His seduction of Helen (the wife of Menelaus, king of Sparta) and refusal to return her was the cause of the Trojan War.
