Gustave Moreau was the leading French Symbolist painter, known for his richly jeweled, mythological compositions that seem to glow from within. His studio in Paris became the Musée Gustave Moreau, and as a professor at the École des Beaux-Arts he taught Matisse, Rouault, and Marquet — shaping the next generation even as his own work explored ancient myths with ecstatic, exotic intensity.
