Bust of Philip II of Spain (back side of the pendant)

1559-62
Onyx, engraved gold and polychrome enamel, 42 x 35 mm
Galleria Palatina (Palazzo Pitti), Florence

This pendant was part of a collection of gems belonging to Duchess Eleanor of Toledo, who purchased it in 1562. It shows the busts of Philip II of Spain (back side) and Don Carlos (front side). The portraits, made on two separate onyx plates separated by silver foil, have been inserted into an elaborate gold mount, decorated with geometric patterns, grotesque motifs and little animals, and enameled using the champlevé technique.

The back side of the pendant depicts the bearded bust of Philip II of Spain, shown in profile, facing the right and wearing a princely suit of parade armour, partly covered by a cloak knotted over his shoulder.

On the front side is the youthful bust of Don Carlos, shown in profile, looking to the left, with an old-fashioned coat and a rich suit of armour, decorated on the shoulder with a lion protome.

The two cameos date back to between 1555, the year in which the medal of Philip II was coined, and 1562, the year in which the Duchess Eleanor purchased the pendant.
