Gianfrancesco Penni
Born in Florence to a family of weavers, Penni entered Raphael's workshop very early in his life, and collaborated with him on several works, including the famous Rooms of the Vatican Palace, as well as the frescoes of Villa Farnesina, both in Rome. Heinrich Wölfflin and some other writers credited him with the entire execution of the Raphael Cartoons, with Raphael only creating the initial design, though more recent writers believe Raphael did much of the work himself.
Le Déjeuner sur l’herbe
As with the later "Olympia" (1863) and other works, Manet's composition reveals his study of the old masters, as the disposition of the main figures is derived from Marcantonio Raimondi's engraving "The Judgment of Paris" (c. 1515) after a drawing by Raphael. Raphael was an artist revered by the conservative members of the Académie des Beaux-Arts and his paintings were part of the teaching programme at the École des Beaux-Arts, where copies of fifty-two images from his most celebrated frescoes were permanently on display. "Le Bain" (an early title for "Le Déjeuner sur l’herbe") was therefore, in many ways, a defiant painting. Manet was cheekily reworking Raphael, turning a mythological scene from one of the most celebrated engravings of the Renaissance into a tableau of somewhat vulgar Parisian holidaymakers.
