Some of the richest pieces of carved walnut furniture belonging to this period are the bellows. As these are characteristic of the Italian style of the period in furniture of various kinds, we give woodcuts of two examples in the South Kensington collection. They are generally of walnut touched with gilding; and in the form still familiar to ourselves, which is as old as the classic times.

Besides furniture carved in this way out of solid wood, there were other materials used and other methods of decorating household furniture. The tarsia or inlaid work has been alluded to. The first methods were by geometrical arrangements of small dies; but magnificent figure designs had been executed in inlaid wood in the early period of the renaissance, and before it. Work of this kind was made in two or three woods, and much of it is in pine or cypress. The large grain is used to express lines of drapery and other movements by putting whole folds or portions of a dress or figure with the grain in one direction or another, as may be required. The picture is thus composed of pieces inclined together; a few bold lines incised and blackened give such outlines of the form as are not attainable by the other method, and slight burning with an iron is sometimes added to produce tone or shadow.

"'Tarsie' or 'Tarsiatura,'" says Mrs. Merrifield, "was a kind of mosaic in woods. This consisted in representing houses and perspective views of buildings, by inlaying pieces of wood of various colours and shades into panels of walnut wood. Vasari speaks rather slightingly of this art, and says that it was practised chiefly by those persons who possessed more patience than skill in design; that although he had seen some good representations in figures, fruits, and animals, yet the work soon becomes dark, and was always in danger of perishing from the worms and by fire. Tarsia work was frequently employed in decorating the choirs of churches as well as the backs of seats and the wainscoting. It was also used in the panels of doors."

Another method of ornamentation dependent on material that came into use in this century was the Pietra Dura or mosaic panelling of hard pebbles. The work is laborious and costly. Not only are the materials (agate, carnelian, amethyst and marbles of all colours) expensive, but each part must be ground laboriously to an exact shape and the whole mosaic fitted together, a kind of refinement of the old marble work called Alexandrinum. Besides being formed into marble panels for table tops and cabinet fronts, pietra dura was let into wood, and helped out with gay colours the more sombre walnut or ebony base of the furniture.

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.
