Hiram Powers was an American neoclassical sculptor. He was one of the first 19th-century American artists to gain an international reputation, largely based on his famous marble sculpture The Greek Slave.

Neoclassicism, also spelled Neo-classicism, emerged as a Western cultural movement in the decorative and visual arts, literature, theatre, music, and architecture that drew inspiration from the art and culture of classical antiquity. Neoclassicism was born in Rome, largely due to the writings of Johann Joachim Winckelmann during the rediscovery of Pompeii and Herculaneum. Its popularity expanded throughout Europe as a generation of European art students finished their Grand Tour and returned from Italy to their home countries with newly rediscovered Greco-Roman ideals. The main Neoclassical movement coincided with the 18th-century Age of Enlightenment, and continued into the early 19th century, eventually competing with Romanticism. In architecture, the style endured throughout the 19th, 20th, and into the 21st century.
