Which artist is celebrated as a neoclassical painter reacting against the Rococo movement?

Jacques-Louis David is celebrated as a neoclassical painter who emerged as a pivotal figure reacting against the Rococo movement. The Rococo style, known for its ornate, playful, and often whimsical characteristics, stood in contrast to the serious and moralistic tone of neoclassicism that David championed.

David's work is characterized by a focus on classical subjects, clear lines, and a sense of grandeur, often drawing inspiration from ancient Rome and Greece. He aimed to convey moral lessons through history painting, emphasizing virtue and sacrifice. This is particularly evident in his famous works such as "Oath of the Horatii" and "Death of Socrates," which reflect themes of patriotism, civic duty, and stoicism.

Through these choices, David elevated the ideals of reason and virtue, promoting an aesthetic that aligned with the political and social changes during the late 18th century, particularly around the time of the French Revolution. His methods and subject matter distinctly contrasted the lighter, frivolous qualities associated with Rococo art, marking him as a leading figure in the neoclassical movement.
