Here you will find our selection of relief sculptures created from antiquity to the early 20th century. A relief is a sculpture in which the image protrudes from the background, in essence making it both two-dimensional and three-dimensional. Bas-relief, or low relief, means the image is only slightly raised. Alto-relief, or high relief, means the image has much more depth and at times could be almost completely in the round. Sunken relief, or incised or intaglio relief, mainly applies to ancient Egyptian art; the low-relief image is placed in a sunken area so that nothing projects beyond the surface.
