A statue is a sculpture representing one or more people or animals (including abstract concepts allegorically represented as people or animals), normally full-length, as opposed to a bust, and at least close to life-size, or larger. A small statue, usually small enough to be picked up, is called a statuette or figurine, while one that is more than twice life-size is called a colossal statue.
The definition of a statue is not always clear-cut; equestrian statues, of a person on a horse, are certainly included, and in many cases, such as a Madonna and Child or a Pietà, a sculpture of two people will also be.
Statues have been produced in many cultures from prehistory to the present; the oldest known statue dating to about 30,000 years ago. The world's tallest statue, Spring Temple Buddha, is 128 metres (420 ft), and is located in Lushan County, Henan, China.
Many statues are built on commission to commemorate a historical event, or the life of an influential person. Many statues are intended as public art, exhibited outdoors or in public buildings. Some statues gain fame in their own right, separate from the person or concept they represent, as with the Statue of Liberty.
Ancient statues often survive showing the bare surface of the material of which they are made. For example, many people associate Greek classical art with white marble sculpture, but there is evidence that many statues were painted in bright colours. Most of the colour was weathered off over time; small remnants were removed during cleaning; in some cases small traces remained which could be identified. A travelling exhibition of 20 coloured replicas of Greek and Roman works, alongside 35 original statues and reliefs, was held in Europe and the United States in 2008: Gods in Color: Painted Sculpture of Classical Antiquity. Details such as whether the paint was applied in one or two coats, how finely the pigments were ground, or exactly which binding medium would have been used in each case—all elements that would affect the appearance of a finished piece—are not known. Richter goes so far as to say of classical Greek sculpture, "`All stone sculpture, whether limestone or marble, was painted, either wholly or in part."
