The Metropolitan Museum of Art has mounted the most comprehensive exhibition possible of Delacroix on this side of the Atlantic. The retrospective, aptly titled “Delacroix,” follows its Paris debut this past summer. In solid collaboration with the Louvre, practically every major work by the French artist that was not too massive, too precious, or simply impossible (his murals) to transport can be seen at The Met until Jan. 6, 2019.
