Rilievo refers to a sculptural technique where the sculpted elements remain attached to a solid background of the same material. It's like a 3D image popping out from a surface, creating a sense of depth. Think of it as the opposite of an engraving, where the design is cut *into* the surface. There are different degrees of rilievo, from low (bas-relief) to high, where the figures are almost detached. Imagine the faces on a coin or the carvings on ancient monuments. It brings art to life by giving it dimension and texture.
