In the fifth chapter of the "Seven Lamps," Section 14, the reader will find the opinion of a modern architect of some reputation, Mr. Wood, that the chief thing remarkable in this church "is its extreme ugliness;" and he will find this opinion associated with another, namely, that the works of the Caracci are far preferable to those of the Venetian painters. This second statement of feeling reveals to us one of the principal causes of the first; namely, that Mr. Wood had not any perception of color, or delight in it. The perception of color is a gift just as definitely granted to one person, and denied to another, as an ear for music; and the very first requisite for true judgment of St. Mark's, is the perfection of that color-faculty which few people ever set themselves seriously to find out whether they possess or not. For it is on its value as a piece of perfect and unchangeable coloring, that the claims of this edifice to our respect are finally rested; and a deaf man might as well pretend to pronounce judgment on the merits of a full orchestra, as an architect trained in the composition of form only, to discern the beauty of St. Mark's. It possesses the charm of color in common with the greater part of the architecture, as well as of the manufactures, of the East; but the Venetians deserve especial note as the only European people who appear to have sympathized to the full with the great instinct of the Eastern races. They indeed were compelled to bring artists from Constantinople to design the mosaics of the vaults of St. Mark's, and to group the colors of its porches; but they rapidly took up and developed, under more masculine conditions, the system of which the Greeks had shown them the example: while the burghers and barons of the North were building their dark streets and grisly castles of oak and sandstone, the merchants of Venice were covering their palaces with porphyry and gold; and at last, when her mighty painters had created for her a color more priceless than gold or porphyry, even this, the richest of her treasures, she lavished upon walls whose foundations were beaten by the sea; and the strong tide, as it runs beneath the Rialto, is reddened to this day by the reflection of the frescoes of Giorgione.
