I’ve recently discovered that Stanford University has one of the Gates of Hell. Fantastic!
The Rodin collection in the connected Cantor Museum has a large selection of Rodin’s smaller works, and gives a really good idea of how Rodin worked, and what he was trying to get at. The Rodin museum in Paris by comparison has more of his monumental work, and is considerably less technical and more autobiographical.
Fun Fact: Pennsylvania is home to one of three original casts of Rodin’s Gates of Hell and is allegedly home to the actual Gates of Hell.
