French sculpture has been an original and influential component of world art since the Middle Ages. The first known French sculptures date to the Upper Paleolithic age. French sculpture originally copied ancient Roman models, then found its own original form in the decoration of Gothic architecture. French sculptors produced important works of Baroque sculpture for the decoration of the Palace of Versailles. In the 19th century, the sculptors Auguste Rodin and Edgar Degas created a more personal and non-realistic style, which led the way to modernism in the 20th century, and the sculpture of Pablo Picasso, Georges Braque, Marcel Duchamp and Jean Arp.
