During the nineteenth century, the French academy of art was a major financial sponsor of painting and sculpture in France; sponsorship by private individuals had decreased dramatically by this time.
Apparent Paradox
Because the academy discouraged innovation in the arts, there was little innovation in French sculpture.
Yet nineteenth century French painting showed a remarkable degree of innovation.
Evaluate
Something that would make sculptors more reliant on the academy than painters could explain why sculpture saw little innovation, while painting showed a remarkable amount of innovation.
