Jeffrey Deitch’s “Luncheon in the Grass” comprises works by more than 30 renowned artists made in response to Édouard Manet’s famed painting Déjeuner sur l’herbe. Completed in 1863, the composition by Manet—detailing two fully clothed men and two nude women on a picnic in a woodland clearing—has long since been considered by art historians to be the first modern painting for its unusual subject matter, its use of unrealistic perspective, and other elements uncommon during that era of painting. In the years since its creation, many artists have offered their own interpretations of the work, with some lending their style to reinterpret the scene, while others have borrowed themes or recontextualized work completely. The presentation (open through April 23) includes works from artists like Alain Jacquet, Robert Colescott, Kehinde Wiley, Cecily Brown, Mickalene Thomas, Tschabalala Self, and Jeff Koons.
