Moreau's main focus was the illustration of biblical and mythological figures. As a painter of literary ideas rather than visual images, he appealed to the imaginations of some Symbolist writers and artists, who saw him as a precursor to their movement.
His father, Louis Jean Marie Moreau, was an architect, who recognized his talent. His mother was Adele Pauline des Moutiers. Moreau studied under François-Édouard Picot and Théodore Chassériau, with whom he may have become lovers; Moreau also carried on a deeply personal 25-year relationship, possibly romantic, with Adelaide-Alexandrine Dureux, a woman whom he drew several times. His first painting was a Pietà which is now located in the cathedral at Angoulême. He showed A Scene from the Song of Songs and The Death of Darius in the Salon of 1853. In 1853 he contributed Athenians with the Minotaur and Moses Putting Off his Sandals within Sight of the Promised Land to the Great Exhibition.
Oedipus and the Sphinx, one of his first symbolist paintings, was exhibited at the Salon of 1864. Over his lifetime, he produced over 8,000 paintings, watercolors and drawings, many of which are on display in Paris' Musée national Gustave Moreau at 14, rue de la Rochefoucauld (IXe arrondissement). The museum is in his former workshop, and was opened to the public in 1903.
Moreau is buried in Paris' Cimetière de Montmartre.
