Alto-relievo is translated from Italian as high-relief, a technique in Classical antiquity sculpture to reveal human or animal figures that project out from a solid tablet of marble or other material. At least one-half of the figure must be projecting from the surface, often appearing in a standing position.
In the illustration at right, the vertical tablet wall is used as a simple reinforcement for the sculpture, with no detail. Frequently the tablet is carved with decorations or detailed inscriptions.
