In the cupola of the duomo of Parma the same painter has represented the Assumption with so much deceptive power, that he has made a dome of some thirty feet diameter look like a cloud-wrapt opening in the seventh heaven, crowded with a rushing sea of angels. Is this wrong? Not so: for the subject at once precludes the possibility of deception. We might have taken the vines for a veritable pergoda, and the children for its haunting ragazzi; but we know the stayed clouds and moveless angels must be man's work; let him put his utmost strength to it and welcome, he can enchant us, but cannot betray. We may thus apply the rule to the highest, as well as the art of daily occurrence, always remembering that more is to be forgiven to the great painter than to the mere decorative workman; and this especially, because the former, even in deceptive portions, will not trick us so grossly; as we have just seen in Correggio, where a worse painter would have made the thing look like life at once. There is, however, in room, villa, or garden decoration, some fitting admission of trickeries of this kind, as of pictured landscapes at the extremities of alleys and arcades, and ceilings like skies, or painted with prolongations upwards of the architecture of the walls, which things have sometimes a certain luxury and pleasureableness in places meant for idleness, and are innocent enough as long as they are regarded as mere toys. XVI. Touching the false representation of material, the question is infinitely more simple, and the law more sweeping; all such imitations are utterly base and inadmissible. It is melancholy to think of the time and expense lost in marbling the shop fronts of London alone, and of the waste of our resources in absolute vanities, in things about which no mortal cares, by which no eye is ever arrested, unless painfully, and which do not add one whit to comfort or cleanliness, or even to that great object of commercial art--conspicuousness. But in architecture of a higher rank, how much more is it to be condemned? I have made it a rule in the present work not to blame specifically; but I may, perhaps, be permitted, while I express my sincere admiration of the very noble entrance and general architecture of the British Museum, to express also my regret that the noble granite foundation of the staircase should be mocked at its landing by an imitation, the more blameable because tolerably successful. The only effect of it is to cast a suspicion upon the true stones below, and upon every bit of granite afterwards encountered. One feels a doubt, after it, of the honesty of Memnon himself. But even this, however derogatory to the noble architecture around it, is less painful than the want of feeling with which, in our cheap modern churches, we suffer the wall decorator to erect about the altar frameworks and pediments daubed with mottled color, and to dye in the same fashions such skeletons or caricatures of columns as may emerge
