Fiercely competitive, Matisse and Picasso engaged in one of the most formidable artistic dialogues of this century. The intense beginning of the relationship between the two artists - from the time they met in 1906 until 1917, when Matisse left for Nice - has already been amply studied, but their continuous exchange during the second part of their career has never been examined in detail. In Matisse and Picasso, Yve-Alain Bois stages the intertwined evolution of the two giants of modern art as if it were an ongoing game of chess between two masters. The postwar period, during which they often met and exhibited together, is the most poignant in their long friendship. It includes monuments such as Picasso's War and Peace murals in Vallauris, which can be read as a response and a homage of sorts to his aging competitor - Matisse's Vence chapel in fact intensely irritated Picasso. Matisse and Picasso's dense plot and rich narrative make this work read more like a suspense novel than a traditional art history treatise.
