INTAGLIO (an Ital. word, from intagliare, to incise, cut into), a form of engraving or carving, in which the pattern or design is sunk below the surface of the material thus treated, opposed to “cameo” or “relievo”—carving or engraving where the design is raised. Intaglio is thus applied to incised gems, as cameo (q.v.) to gems cut in relief (see Gems).
