Another distinctly human aspect of art interests Browning, and that is its power to represent and so to recall a vanished civilization. Greek statues, the devotional pictures of the early Florentines, the work of the later Italian realists, stand, in "Old Pictures in Florence," as representatives of the life and thought that produced them. In "A Toccata of Galuppi's" the music revivifies the superficial gaiety, the undertone of fear, in the life of eighteenth century Venice. Highly significant in this connection are the poems in which he traces the evolution of art. Running through "Old Pictures in Florence" and "Fra Lippo Lippi" we find an ordered statement of the chief changes in the ideals of art as Browning saw them. The Greeks, we are told, had produced in sculpture the most beautiful representations of the human body. But if their successors had been content merely to admire this perfect achievement, they would have purchased satisfaction at the price of their own arrested development. Progress came only when, in the dawn of Italian art, men turned from Greek perfection, from the supremely beautiful but limited representations of the human body, to an attempt to paint the invisible, the spiritual side of man's nature. The work of these artists was great because it was not imitative and because it stretched toward an unending and ideal future. But the idealistic and aspiring temper of early Tuscan art had the defects of its qualities. Its spiritual ecstasy once conventionalized and reduced to a formula led to unreality, and, if not to untruth, at least to an unwholesome ignoring of a part of truth. There was, therefore, an inevitable reaction to the naturalism described with such verve and gusto by Fra Lippo Lippi. But this is, after all, social history in terms of art, and to Browning what has happened in painting is of value chiefly as showing concretely what has happened in the mind of man. From the instances already cited it is apparent that Browning's interest centered, not in abstract or theoretical discussions of human problems, but in the individuals who face the problems. In this point Browning is sharply distinguished from his poetic contemporaries as a class. They felt deeply "all the weary weight of this unintelligible world," so deeply that while they gave much thought to ideals of social amelioration, few of them presented individuals with any dramatic distinctness. Browning stands practically by himself in the nineteenth century as the poet who gives us both the "doubter and the doubt," who is able to join with an impressive statement of the hopes and fears of man, an equally impressive sequence of individual men and women. In this he harks back to the broad inclusiveness of the Elizabethan dramatists. In contemporary literature, his nearest congeners are in fiction, not in poetry.
