From a Christie’s online article:
Rodin first exhibited a bronze and a plaster version of The Age of Bronze at the Cercle Artistique in Brussels in January 1877. A few months later, he exhibited the plaster at the Paris Salon, where it caused a scandal. ‘The vitality and naturalism of the sculpture was so extreme, the sense of modelling so observed, that he was accused of having cast the sculpture from the model himself,’ says the specialist.
Tudor Davies, Head of Impressionist & Modern Art in Paris, reveals why Rodin’s Salon ‘scandal’ marked a pivotal turning point in the artist’s career.
The Age of Bronze was originally conceived in 1877, and is widely considered Rodin’s first great work, ranking alongside his later masterpieces, including La Porte de l’Enfer, Le Penseur and Le Baiser. Its conception marked a decisive turning point in the sculptor’s career.
