Roman Emperor on Horseback and His Slave Hit by Lightning

Théodore Chassériau's 1855 Roman Emperor on Horseback and His Slave Hit by Lightning belongs to his late period, when the artist was producing ambitious large-format works that synthesized his complex inheritance from both Ingres and Delacroix — the twin masters between whom his entire career had navigated. The equestrian imperial subject, inflected by the supernatural event of lightning, creates a dramatic encounter between human power and divine or natural force that was characteristic of Romanticism's attraction to extremity and sublimity. Chassériau had visited Algeria in 1846 and the experience permanently inflected his palette and his taste for dramatic subjects involving figures on horseback. By 1855 he was near the end of his short life — he died in 1856 aged thirty-seven — and this late work demonstrates both the ambition and the intensified coloristic approach of his maturity. The Louvre's holding of this painting confirms Chassériau's status within the French national collection, his work occupying a transitional position between strict neoclassicism and fully developed Romanticism.

The equestrian composition presents the classic challenge of integrating a rearing or dramatic horse with a human figure and a narrative element — here the lightning bolt and the slave. Chassériau's coloristic approach by 1855 is warmer and more saturated than his early work under Ingres, closer to Delacroix in its atmospheric richness, though his drawing retains the classical linearity of his first training.
