"Mezzo-relievo" (or "mezzo-rilievo") refers to a type of relief sculpture where the figures project moderately from the background. It's a middle ground between high relief (alto-relievo) and low relief (bas-relief). Think of it as a 3D image that is not quite fully detached from its background. The figures are raised enough to create strong shadows and visual interest. It's a common technique in classical sculpture.
