The French artist Jacques Louis David was many things. The king of Neoclassicism. Napoleon’s appointed painter. A fabulous portraitist. David first appeared in the public eye in the 1780s, when his painting Oath of the Horatii created a sensation. In the early years of the Revolution, he was a member of Robespierre’s extremist Jacobin group and was nicknamed “the Robespierre of the Brush.” When Louis XVIII came to power, David left France for self-exile in Brussels. He died in 1825, when struck by a carriage. This is the first exhibition devoted to David’s works on paper. Preparatory studies as well as his monumental successes are also on view. —E.C.
