As one has, however, so often occasion to note in France—where in every field of intellectual effort the influence of schools and groups and movements is so great that almost every individuality, no matter how strenuous, falls naturally and intimately into association with some one of them—there is every now and then an exception that escapes these categories and stands quite by itself. In modern painting such exceptions, and widely different from each other as the poles, are Couture and Puvis de Chavannes.
