Focus on this artwork and explain the Casts.
The Thinker has been cast in multiple versions and is found around the world, but the history of the progression from models to castings is still not entirely clear. About 28 monumental-sized bronze casts are in museums and public places. In addition, there are sculptures of different study-sized scales and plaster versions (often painted bronze) in both monumental and study sizes. Some newer castings have been produced posthumously and are not considered part of the original production.
Rodin made the first small plaster version around 1881. The first full-scale model was presented at the Salon des Beaux-Arts in Paris in 1904. A public subscription financed a bronze casting, which became the property of the City of Paris, and was put in front of the Panthéon. In 1922, the original bronze was moved to the Musée Rodin.
