Such was the ingenuity that prepared, and such the genius that raised to its height the fabric of modern art. Before we proceed to the next epoch, let us make an observation. Form not your judgment of an artist from the exceptions which his conduct may furnish, from the exertions of accidental vigour, some deviations into other walks, or some unpremeditated flights of fancy, but from the predominant rule of his system, the general principle of his works. The line and style of Titian's design, sometimes expand themselves like those of Michael Angelo. His Abraham prevented from sacrificing Isaac; his David adoring over the giant-trunk of Goliath; the Friar escaping from the murderer of his companion in the forest, equal in loftiness of conception and style of design, their mighty tone of colour and daring execution: the heads and groups of Raphael's frescoes and portraits sometimes glow and palpitate with the tints of Titian, or coalesce in masses of harmony, and undulate with graces superior to those of Correggio; who in his turn once reached the highest summit of invention, when he embodied silence and personified the mysteries of love in the voluptuous group of Jupiter and Io; and again exceeded all competition of expression in the divine features of his Ecce-Homo. But these sudden irradiations, these flashes of power are only exceptions from their wonted principles; pathos and character own Raphael for their master, colour remains the domain of Titian, and harmony the sovereign mistress of Correggio.
