Who commissioned Fragonard to paint "The Swing"?

The commission for Fragonard's famous painting "The Swing" indeed came from Baron de Saint-Julien, who was a wealthy amateur art collector and a prominent member of the French aristocracy in the 18th century. This period was marked by a shift towards Rococo style, emphasizing themes of romance and playful sensuality, which are central to the painting.

Baron de Saint-Julien's choice to commission Fragonard demonstrates his interest in the Rococo aesthetic and themes, reflected in the light-hearted, flirtatious scene depicted in the work. The painting is not just a personal commission; it also illustrates the social dynamics and leisure activities of the French upper class during that era. In contrast, the other individuals mentioned were not connected to the commission of this specific work, and therefore do not relate to the question about "The Swing." Understanding the context of the commission helps in grasping the significance of the artwork within the period's artistic movements and social milieu.
