His works often depicted intense human emotions and dramatic scenes, reflecting the broader themes of Romanticism, which emphasized individual experience, nature, and the sublime. Géricault's most famous painting, 'The Raft of the Medusa,' exemplifies these themes and showcases his innovative approach to composition and narrative in visual art.
