Auguste Rodin‘s The Thinker was originally conceived to be a part of The Gates of Hell, his sculptural group depicting a scene from Dante Alighieri‘s Inferno, but several larger bronze versions were created later. This version was installed outside the Cleveland Museum of Art in 1917. It is one of less than ten created under Rodin’s supervision.

This particular version of The Thinker also has an interesting history. In 1970, a pipe bomb was planted at the base of the statue and the resulting explosion damaged the work. The perpetrators remain a mystery to this day.
