David, therefore, stages the death of his friend, which occurred while writing and taking one of his cold baths (it has been considered that Marat suffered from psoriasis). Also, this painting represents in a manifestly allegorical way what he considered a crime against France and against a patriot. In this last sense, the painter builds a political work of the first order, staging for the people a martyr of the Revolution, providing an iconic image with which to feed the revolutionary symbolism of the classes for which the martyr, Marat, had coined a name, "le petit peuple."
