high relief

High relief is a sculptural technique where figures project significantly from a supporting background, often at least half of their natural circumference. This projection can be so substantial that parts of the figure may appear completely detached from the background, nearing the appearance of sculpture in the round.12

This contrasts with low relief (bas-relief), where the projection is minimal, and high relief, where forms project at least half their natural circumference from the background. High relief became prominent in ancient Greek sculpture, notably in decorations for classical temples like the Parthenon. This technique allows for dramatic and dynamic compositions, with figures appearing to emerge from the surface. Renaissance artists like Lorenzo Ghiberti and Donatello further explored the interplay between high and low relief to create illusions of depth and space.234
