Intarsia is a form of wood inlaying that is similar to marquetry. The start of the practice dates from before the seventh century AD. The technique of intarsia inlays sections of wood within the solid wood matrix of floors and walls or of tabletops and other furniture; by contrast marquetry assembles a pattern out of veneers glued upon the carcass. The word intarsia may derive from the Latin word interserere.
