One of these objects sitting in front of a silver plate on a shelf is one of many symbols of affluence in the background of Quentin Matsys's The Money Changer and his Wife. One of them is held by a contented, long-haired two-year-old Raoul Levert in one of the final paintings by Vincent van Gogh. Camille Lefèvre designed a pair of oval galleries for a Paris museum named for these objects. (15[1])These objects and (*) flowers (10[1])are the brightest elements at the top edge of a painting in which some of them are occluded by a cloud that Mercury pokes with his caduceus. Four of these expensive, imported objects sit on the sideboard and windowsill at the left of the Arnolfini Wedding. These objects' similarity to the orbs on the Medici coat of arms may be why Sandro Botticelli set Primavera in a grove of trees that grow, for 10 points, what citrus fruit? ■END■
