more vague than the most definite thoughts men have had through three centuries on a matter that has been so near their hearts, the new body--a passing light, a mere intangible, external effect, over those too rigid, or too formless faces; a dream that lingers a moment, retreating in the dawn, incomplete, aimless, helpless; a thing with faint hearing, faint memory, faint power of touch; a breath, a flame in the doorway, a feather in the wind. The qualities of the great masters in art or literature, the combination of those qualities, the laws by which they moderate, support, relieve each other, are not peculiar to them; but most often typical standards, or revealing instances of the laws by which certain aesthetic effects are produced. The old masters indeed are simpler; their characteristics are written larger, and are easier to read, than the analogues of them in all the mixed, confused productions of the modern mind. But when once we have succeeded in defining for ourselves those characteristics, and the law of their combination, we have acquired a standard or measure which helps us to put in its right place many a vagrant genius, many an unclassified talent, many precious though imperfect [97] products of art. It is so with the components of the true character of Michelangelo. That strange interfusion of sweetness and strength is not to be found in those who claimed to be his followers; but it is found in many of those who worked before him, and in many others down to our own time, in William Blake, for instance, and Victor Hugo, who, though not of his school, and unaware, are his true sons, and help us to understand him, as he in turn interprets and justifies them. Perhaps this is the chief use in studying old masters. 1871. LEONARDO DA VINCI HOMO MINISTER ET INTERPRES NATURAE
