Altorilievi are artistic sculptures or carvings that protrude from a flat surface, adding a three-dimensional effect to the artwork. Synonyms for altorilievi include bas-reliefs, high reliefs, low reliefs, and sunken reliefs. Bas-reliefs are sculptures where the design is carved into a flat surface, with the protruding elements gradually receding in depth. High reliefs, on the other hand, have a deep perspective, with the carved elements jutting out boldly. Low reliefs have a similar effect to bas-reliefs, but with subtler details. Sunken reliefs create an inverted effect, with the carved image appearing to be sunk into the surface. All these synonyms for altorilievi offer artists diverse options to express their creativity, skills, and imagination.
