Neoclassicism. A nineteenth century French art style and movement that originated as a reaction to the Baroque. It sought to revive the ideals of ancient Greek and Roman Art. Neoclassic artists used classical forms to express their ideas about courage, sacrifice, and love of country. Though sometimes the terms Classicism and Neoclassicism are used interchangeably, in the context of the tradition Classicism refers either to the art produced in antiquity or to later art inspired by antiquity, and Neoclassicism refers only to the art produced later but inspired by antiquity.
