Before leaving the Italian sixteenth-century work we must notice the mirrors, with their elaborately carved frames of Venetian design and manufacture. In this century Venice was renowned for the making of glass, for which it is still famous, and certain privileges were granted by the State exclusively to Venetian manufacturers of looking-glasses. Two Murano glass makers named Andrea and Dominico, who were the inventors, were granted in the year 1507 the sole privilege of making “mirrors of crystal glass” for a term of twenty years. Previous to this time the mirrors were made of various polished metals. The frames of the Venetian mirrors were often elaborately carved (Fig. 242), some of them being made in designs that were strictly architectural in character, representing a door, or window frame, with pilasters, frieze, and cornice, and sill or plinth. These carved frames were often partly or wholly gilt, and were exported in considerable quantities. Pictures were framed in a similar way to the mirrors, and carved and gilt frames were soon used all over Europe as picture frames. Later on gilt furniture of all kinds was made in Venice and was in great favour in the other countries of the Continent. [Illustration: Fig. 242.—Venetian Minor Frame; Sixteenth Century. (P.)] The manufacture of marquetry furniture by the Dutch in the seventeenth century has been mentioned as having helped in a great measure to change the style of furniture design from its former architectural character to a greater simplicity of construction. Large panel surfaces were used for the purpose of showing to greater advantage the rich and bright colours of different kinds of hard woods used in the marquetry. Both natural and stained varieties of various wood were arranged in the designs in juxtaposition, and a free and picturesque kind of ornamental foliage was employed mixed with large tulips, roses, and birds in the Dutch marquetry decoration. Other materials, such as ivory, ebony, and mother-of-pearl, were also used as inlays. In France a similar kind of marquetry was developed, but the design consisted more of figure subjects and imitations of ruins in landscapes. A complete change in the design of the furniture in the latter country was also effected by the same desire to get large surfaces on which the inlaid work could be seen to great advantage, and the spaces were not divided by architectural mouldings, or pilasters, as they had been in the preceding earlier work. Towards the end of the sixteenth century, and during the earlier half of the seventeenth, the sumptuous furniture, the beds, and general furnishing of the better class of houses and palaces in France and other European countries, were characterized by the use of costly silk brocades, tissues, and embroidered coverings and hangings.
