This tabletop is distinguished from contemporary florentine works inlaid with stone by the central alabaster oal flanked by roundels of a marble called breccia di Tivoli. The geometric design is characteristic of pietre dure made about 1600 in papal Rome. Strapwork cartouches recalling forged iron are held in place by four lapis lazuli bolts, strenthening the optical illusion. The extensive use of bianco antico and nero antico–white- and black-beined marble–is unusual, the choice of a bold artisan. The severity of the inner decoration seems to translate jewelry designs from contemporary pattern books into a monumental work of art framed by a playful border depicting wild animals, blossoms emitting seeds like strings of pearls, leafy scrollwork, and floral sprays. Most of these motifs dervice from ancient Roman mosaics.
