Sculpture is any three-dimensional form created as an artistic expression. Sculpting is the art of assembling or shaping an object. It may be of any size and of any suitable material. The artist who does this is called a sculptor.
Sculpture is among the oldest of the arts. Even before painting cave walls, early humans fashioned shapes from stone. From these beginnings, artifacts have evolved to their current complexity. The point at which they became art is for the beholder to decide. In any case, sculptures place among the greatest of human achievements.
