Intarsia Panel; Castle Interior; 1800-1858. Maker: Luigi Ravelli (1776-1858). The technique of using inlaid marquetry to create a perspective picture in wood is known as intarsia. This panel is the work of the Italian craftsman; Luigi Ravelli (1776-1858). Considerable skill was needed to select the appropriate grain and figure from the many different veneers used to create these works; in order to achieve the subtle variations of texture in the finished picture. Ravelli has also used controlled burning to produce the effect of shade. This was done by scorching areas of veneer in a tray of hot silver sand.
