Mezzo-relief is a sculptural technique that falls between high relief and low relief. In mezzo-relief, the figures or elements project from the background but not as prominently as in high relief. This allows for a more subtle three-dimensional effect, where the depth and detail can be appreciated from various angles. This technique is often used in decorative arts and architecture, enhancing surfaces without overwhelming them. Artists may employ mezzo-relief in works such as friezes or plaques, where the interplay of light and shadow adds depth while maintaining a cohesive design with the surrounding space.
