The Thinker by Auguste Rodin

The Thinker

The Thinker (French: Le Penseur) is a bronze sculpture by Auguste Rodin, usually placed on a stone pedestal. The work shows a nude male figure at about life-size sitting on a rock with his chin resting on one hand as though deep in thought, and is often used as an image to represent philosophy. There are about 28 full size castings, in which the figure is about 186 centimetres (73 in) high, though not all were made during Rodin's lifetime and under his supervision, as well as various other versions, several in plaster, studies, and posthumous castings, in a range of sizes. Rodin first conceived the figure as part of another work in 1880, but the first of the familiar monumental bronze castings did not appear until 1904.
