From the collections of the Metropolitan Museum of Art, this is a terra cotta model that Clodion (Claude Michel) sculpted in Paris around 1784. He was proposing a large monument to the invention of the balloon. The Met’s webpage offers several more views of the model.
I love the combination of the latest and greatest science of the day with mythological figures. Winged cherubim gather fuel to make the balloon launch, and winged angels trumpet the achievement.
You’d think with all those wings, the cherubs and angels wouldn’t be that impressed by ballooning. “Oh, you can get off the ground now. That’s lovely. Can you decide which direction to go? No? Well, keep working on that. We’ll be over here. Or over here. Or wherever we choose, you see.”
