The Spanish city of Merida has some spectacular Roman ruins, including one of the ancient world’s best preserved hippodromes for chariot races. In the archaeological museum are many chariot racing-related works of art, including this mosaic of a triumphant charioteer named Marcian. The text above says, simply, ‘Marcian Wins’! His lead horse’s name is also recorded (INUMINATOR), and the name of the stable he was from (GETULI). Very likely, the patron who had this huge floor mosaic in his villa was the owner of both Marcian–charioteers were almost always slaves–and the horses as well. His floor mosaic was a big billboard advertising his successes as much as Marcian’s.
