A statue is a sculpture in the round representing a person or persons, an animal, or an event, normally full-length, as opposed to a bust, and at least close to life-size, or larger. Its primary concern is representational.
The definition of a statue is not always clear-cut; sculptures of a person on a horse, called Equestrian statues, are certainly included, and in many cases, such as a Madonna and Child or a Pietà , a sculpture of two people will also be. A small statue, usually small enough to be picked up, is called a statuette or Figurine.
