This panel features several stories from the turbulent life of the Trojan prince, Paris. The prince's first wife, the nymph Oenone, appears at center, wearing a flowing brocaded gown and carrying a bow. Blessed with the gift of prophecy, Oenone foretold to Paris the dire consequences of his pursuit of the beautiful Spartan queen, Helen. The left-hand side of the panel shows the Judgment of Paris. Here, a reclining Paris hands a golden apple to Venus--one of three bare-breasted goddesses--in exchange for access to Helen. Oenone reappears on the right-hand side, imploring Paris, already mounted on a white horse, not to abandon her. In the distance, Paris, alone on horseback, gallops toward the turreted red walls of a city, possibly Troy, and his fateful future.
Two smaller panels containing full-length figures of Paris and Oenone dressed in armor originally flanked this central panel. These panels comprised part of a cassone, or wedding chest. In the fashion of his native Siena, a center of cassoni production, Francesco di Giorgio Martini decorated many such chests with elaborate mythological tales.
