In contrast to the Neoclassical perfectionism of his chief rival Ingres, Delacroix took for his inspiration the art of Rubens and painters of the Venetian Renaissance, with an attendant emphasis on color and movement rather than clarity of outline and carefully modeled form. Dramatic and romantic content characterized the central themes of his maturity, and led him not to the classical models of Greek and Roman art, but to travel in North Africa, in search of the exotic. Friend and spiritual heir to Théodore Géricault, Delacroix was also inspired by Byron, with whom he shared a strong identification with the "forces of the sublime", of nature in often violent action.
