The assassination of Julius Caesar on the Ides of March, 44 BC, has been painted repeatedly across five centuries of European art, and the accumulated versions constitute a case study in how the same historical event can be made to mean entirely different things depending on the visual choices made around it. The event is fixed: Caesar was killed in the Theater of Pompey by a group of senators. The meaning of the event — was it tyrannicide or murder, liberation or catastrophe — has been contested ever since, and the paintings rehearse that contest in visual terms.
