In the main hall of the Musée d’Orsay in Paris, beneath the vast iron-and-glass vault of the former railway station, stands a bronze that makes explicit what Gérôme’s paintings kept implicit. A man in contemporary nineteenth-century dress — smock, trousers, the clothes of a working artist — stands beside a Roman gladiator. The gladiator is armored, helmeted, standing over a fallen opponent whose arm is raised in the gesture of submission. The contemporary figure reaches toward the gladiator with a sculptor’s tool. This is Jean-Léon Gérôme’s self-portrait with his own creation: the artist inside the ancient world he spent his career constructing, the boundary between the nineteenth century and the Roman arena dissolved by the act of making.
