This rectangular chest with hinged cover is embellished with a technique called "certosina" (from the works made at Certosa di Pavia): the decoration is inlaid with micromosaic of ivory and ebony, forming traditional geometric patterns which cover every side of the chest, included the inside of the cover. This decoration is tipical of the Nasirid school and is commonly found in other artworks like rugs and fabrics. The inside of the chest has two long compartments with their own lids, and writing instruments were probably kept inside them. A square chessboard is painted on the cover of the chest, and this means that the object was also used as game table. Key is included. A similar object was auctioned by Sotheby's London last 7th October (lot 323), and another one is located in Victoria and Albert Museum (museum number 7224-1860). The chest is in excellent conditions.
