Whilst the superior principles of the art were receiving the homage of Tuscany and Rome, the inferior but more alluring charm of colour began to spread its fascination at Venice, from the pallet of Giorgione da Castel Franco[38], and irresistibly entranced every eye that approached the magic of Titiano Vecelli of Cador.[39] To no colourist before or after him, did Nature unveil herself with that dignified familiarity in which she appeared to Titiano. His organ, universal and equally fit for all her exhibitions, rendered her simplest to her most compound appearances with equal purity and truth. He penetrated the essence and the general principle of the substances before him, and on these established his theory of colour. He invented that breadth of local tint which no imitation has attained; and first expressed the negative nature of shade: his are the charms of glazing, and the mystery of reflexes, by which he detached, rounded, connected, or enriched his objects. His harmony is less indebted to the force of light and shade, or the artifices of contrast, than to a due balance of colour, equally remote from monotony and spots. His backgrounds seem to be dictated by nature. Landscape, whether it be considered as the transcript of a spot, or the rich combination of congenial objects, or as the scene of a phænomenon, dates its origin from him: he is the father of portrait-painting, of resemblance with form, character with dignity, and costume with subordination. Another charm was yet wanting to complete the round of art--harmony: it appeared with Antonio Læti,[40] called Correggio, whose works it attended like an enchanted spirit. The harmony and the grace of Correggio are proverbial: the medium which by breadth of gradation unites two opposite principles, the coalition of light and darkness by imperceptible transition, are the element of his style.--This inspires his figures with grace, to this their grace is subordinate: the most appropriate, the most elegant attitudes were adopted, rejected, perhaps sacrificed to the most awkward ones, in compliance with this imperious principle: parts vanished, were absorbed, or emerged in obedience to it. This unison of a whole, predominates over all that remains of him, from the vastness of his cupolas to the smallest of his oil-pictures.--The harmony of Correggio, though assisted by exquisite hues, was entirely independent of colour: his great organ was chiaroscuro in its most extensive sense; compared with the expanse in which he floats, the effects of Lionardo da Vinci are little more than the dying ray of evening, and the concentrated flash of Giorgione discordant abruptness. The bland central light of a globe, imperceptibly gliding through lucid demitints into rich reflected shades, composes the spell of Correggio, and affects us with the soft emotions of a delicious dream.
