Rodin made the following comment about The Thinker. "Dante sat down on the rock in front of the gates and became absorbed in poetic reverie. Behind him were Ugolino, Francesca, Paolo and all the other characters of the Divine Comedy. This plan was never realized. The anguished form of Dante's thin body isolated from the whole was meaningless. Following my initial inspiration, I then thought of another pensive figure. A naked man sits lost in thought on a rock, with both legs drawn up and his fist resting against his teeth. The work inspires a slow consideration of the beautiful thoughts that fill his head. He is not an idle dreamer. Rather, he is a creator."The physical expression and form of The Thinker, like Adam's, reveal the influence of Michelangelo. Figures such as the prophet Jeremiah in the Sistine Chapel ceiling frescos, and Lorenzo de Medici on the Medici tomb in San Lorenzo Chapel come to mind. Another work that exerted a direct influence was Carpeaux's Ugolino (1863). The image of the right elbow resting on the left thigh is surprisingly similar to Carpeaux's work. The work by Carpeaux, however, was actually executed in Rome under the direct influence of Michelangelo.This gigantic bronze figure was enlarged between 1902-04 by Rodin's collaborator Henri Lebossé on the basis of Rodin's model from 1880. The Thinker, set apart from The Gates of Hell, does not depict an individual thinking figure, but rather represents a universal image of mankind.
