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. 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.
