Final answer:
Artists moved away from Rococo design and developed Neoclassicism due to the perception of immorality and indecency in Rococo art. Neoclassical artists sought inspiration from Nicolas Poussin and aimed for moral, instructive art that emphasized clarity, logic, order, and line over color.
Step-by-step explanation:
During the Rococo period, artists like Jean-Honoré Fragonard and François Boucher created art that was perceived as immoral and indecent. This led to a shift towards Neoclassicism, which was considered more moral and instructive. Neoclassical artists, such as Jacques-Louis David, sought inspiration from Nicolas Poussin, whose work emphasized clarity, logic, order, and line over color. Neoclassicism also drew from the values of ancient Greece and Rome, favoring simplicity and symmetry in architecture, sculpture, and the decorative arts.
