Vasari, speaking of particular pieces of furniture of his day, mentions a "splendid library table" made at the expense and by the order of Francesco de' Medici in Florence. This table was "constructed of ebony," that is, veneered with ebony, "divided into compartments by columns of heliotrope, oriental jasper, and lapis lazuli, which have the bases and capitals of chased silver. The work is furthermore enriched with jewels, beautiful ornaments of silver, and exquisite little figures, interspersed with miniatures and terminal figures of silver and gold, in full relief, united in pairs. There are, besides, other compartments formed of jasper, agates, heliotropes, sardonyxes, carnelians, and other precious stones." This piece was the work of Bernardo Buontalenti. Another piece of such work is described as a table "wholly formed of oriental alabaster, intermingled with great pieces of carnelian, jasper, heliotrope, lapis, and agate, with other stones and jewels, worth twenty thousand crowns." Another artist, Bernardino di Porfirio of Leccio, executed an "octangular table of ebony and ivory inlaid with jaspers." This precious manufacture has been patronised in the grand ducal factories down to recent times, and is continued in the royal establishments of the king of Italy. A feature which was strongly developed in the sixteenth century furniture is the architectural character of the outlines. It has already been observed that in the fifteenth century, chests, screens, stall fronts, doors and panelling followed or fell into the prevailing arrangements of architectural design in stonework, such as window tracery, or wall tracery. But in the cinquecento furniture an architectural character, not proper to woodwork for any constructive reasons, was imparted to cabinets, chests, &c. They were artificially provided with parts that imitated the lines, brackets, and all the details of classic entablatures which have constructive reasons in architecture, but which, reduced to the proportions of furniture, have not the same propriety. These subdivisions brought into use the art of "joinery." The parts obviously necessary for the purpose of framing up wood, whether a box or chest, a door, a piece of panelling, or a chair, offer certain opportunities for mouldings or carvings; some are the thicker portions forming the frames, some the thin flat boards that fill up the spaces. To add a variety of mouldings, such as subdivide the roofs of temples or their peristyles, is, of course, to depart from the carpenter's province and work, and rather to take furniture out of its obvious forms for the express purpose of impressing on it the renaissance type.
