High-relief is a sculptural technique where the figures or elements project significantly from the background, creating a three-dimensional effect. In high-relief works, the depth of the projection can be more than half of the actual figure's thickness, allowing for dramatic shadows and highlights. This technique is often used in classical sculptures and architectural friezes to enhance visual impact. Artists use high-relief to convey movement and emotion, making the subjects appear more lifelike. Common materials for high-relief sculptures include stone, metal, and wood. This style can be found in various cultures, from ancient Roman to Renaissance art, showcasing its enduring appeal in artistic expression.
