Step-by-step explanation:
The painting The Oath of the Horatii by Jacques-Louis David is an exemplar of the Neoclassical style. David's artwork is renowned for its clean lines, clear composition, and the way it emphasizes straightforward storytelling, all characteristic of Neoclassical art. Painted in 1784 and exhibited at the Paris Salon of 1785, David's Neoclassical approach was a response to the earlier Rococo style and was symbolic of Enlightenment ideals, reflecting a desire for rationality, civic duty, and austerity reminiscent of Republican Rome.
Moreover, David's masterpiece gained acclaim not only for its artistic merit but also for its political implications, as it was commissioned by King Louis XVI ahead of the French Revolution. The painting became a catalyst for providing the French populace with an example of self-sacrifice to the State, which was an integral theme during the turbulent times leading up to the revolution.
