exemplified them in the Greek cross, in which these faults appear the most strongly; but they appear in some degree in all sorts of crosses. Indeed, there is nothing more prejudicial to the grandeur of buildings than to abound in angles; a fault obvious in many; and owing to an inordinate thirst for variety, which, whenever it prevails, is sure to leave very little true taste. SECTION X. MAGNITUDE IN BUILDING. To the sublime in building, greatness of dimension seems requisite; for on a few parts, and those small, the imagination cannot rise to any idea of infinity. No greatness in the manner can effectually compensate for the want of proper dimensions. There is no danger of drawing men into extravagant designs by this rule; it carries its own caution along with it. Because too great a length in buildings destroys the purpose of greatness, which it was intended to promote; the perspective will lessen it in height as it gains in length; and will bring it at last to a point; turning the whole figure into a sort of triangle, the poorest in its effect of almost any figure that can be presented to the eye. I have ever observed, that colonnades and avenues of trees of a moderate length were, without comparison, far grander than when they were suffered to run to immense distances. A true artist should put a generous deceit on the spectators, and effect the noblest designs by easy methods. Designs that are vast only by their dimensions are always the sign of a common and low imagination. No work of art can be great, but as it deceives; to be otherwise is the prerogative of nature only. A good eye will fix the medium betwixt an excessive length or height (for the same objection lies against both), and a short or broken quantity: and perhaps it might be ascertained to a tolerable degree of exactness, if it was my purpose to descend far into the particulars of any art. SECTION XI. INFINITY IN PLEASING OBJECTS. Infinity, though of another kind, causes much of our pleasure in agreeable, as well as of our delight in sublime images. The spring is the pleasantest of the seasons; and the young of most animals, though far from being completely fashioned, afford a more agreeable sensation than the full-grown; because the imagination is entertained with the promise of something more, and does not acquiesce in the present object of the sense. In unfinished sketches of drawing, I have often seen something which pleased me beyond the best finishing; and this I believe proceeds from the cause I have just now assigned. SECTION XII. DIFFICULTY.
