Monet’s beloved garden of Giverny was a source of unending inspiration. Nymphéas en fleur is among the largest scale, most brilliantly colored, and vigorously worked canvases that the artist executed – a glorious tribute to the natural world (estimate in the region of $35 million). This work belongs to a group of paintings Monet painted in a burst of untrammeled creativity between 1914 and 1917, as Europe plunged into the chaos of war. Upon the recommendation of Alfred Barr, the first director of the Museum of Modern Art, Peggy and David Rockefeller visited the Parisian dealer Katia Granoff and purchased the present painting in 1956. “One, which was almost certainly painted in the late afternoon and in which the water is a dark purple and the lilies stand out a glowing white, we bought immediately,” David Rockefeller recalled in Memoirs.
