I proceed to consider intrinsic beauty blended with that which is relative. A cube in itself is more agreeable than a parallelopipedon, which will constantly hold in small figures. But a large building in the form a cube, appears lumpish and heavy; while the other figure, set on its smaller base, is by its elevation more agreeable: and hence the beauty of a Gothic tower. But let us suppose this parallelopipedon destin’d for a dwelling house, to make way for relative beauty. Here utility prevails over elevation and a parallelopipedon, inconvenient by its height, is set upon its larger base. The loftiness is gone; but that loss is more than compensated by additional convenience; and for that reason the form of a building spread more upon the ground than raised in height, is always preferred for a dwelling-house, without excepting even the most sumptuous palace.

With respect to the divisions within, utility requires that the rooms be rectangular; for otherwise void spaces will be left of no use. A hexagonal figure leaves no void spaces; but then it determines the rooms to be all of one size, which is extremely inconvenient. A cube will at first be pronounced the most agreeable figure; and this may hold in a room of a moderate size. But in a very large room, utility requires a different figure. The chief convenience of a great room, is unconfined motion. This directs us to the greatest length that can be obtained. But a square room of a great size is inconvenient, by removing far from the hand, chairs and tables, which, when unemploy’d, must be ranged along the sides of the room. Utility therefore requires a large room to be a parallelogram. This figure, at the same time, is the best calculated for receiving light; because, to avoid cross-light, all the windows ought to be in one wall; and if the opposite wall be at such distance as not to be fully lighted, the room must be obscure. The height of a room exceeding nine or ten feet, has little or no relation to utility; and therefore proportion is the only rule for determining the height when above that number of feet.

As all artists who deal in the beautiful are naturally prone to entertain the eye, they have great opportunity to exert their taste upon palaces and sumptuous buildings, where, as above observed, intrinsic beauty ought to have the ascendant over that which is relative. But such propensity is unhappy with respect to private dwelling-houses; because in these, relative beauty cannot be display’d in any perfection, without abandoning intrinsic beauty. There is no opportunity for great variety of form in a small house; and in an edifice of this kind, internal convenience has not hitherto been happily adjusted to external regularity. I am apt to believe, that an accurate coincidence here, is beyond the reach of art. And yet architects always split upon this rock; for they never will give over attempting to reconcile these two incompatibles. How else should it be accounted for, that of the endless variety of private dwelling-houses, there is not one to be found, that is generally agreed upon as a good pattern? The unwearied propensity to make a house regular as well as convenient, forces the architect, in some articles, to sacrifice convenience to regularity, and in others, regularity to convenience. By this means, the house, which turns out neither regular nor convenient, never fails to displease. The faults are obvious, and the difficulty of doing better is known to the artist only[87].

Nothing can be more evident, than that the form of a dwelling-house ought to be suited to the climate; and yet no error is more common, than to copy in Britain the form of Italian houses; not forgetting even those parts that are purposely contrived for air, and for excluding the sun. I shall give one or two instances. A colonnade along the front of a building, hath a fine effect in Greece and Italy, by producing coolness and obscurity, agreeable properties in warm and luminous climates. The cold climate of Britain is altogether averse to this ornament. A colonnade therefore, can never be proper in this country, unless when employ’d to communicate with a detached building. Again, a logio opening the house to the north, contrived in Italy for gathering cool air, is, if possible, still more improper for this climate. Scarce endurable in summer, it, in winter, exposes the house to the bitter blasts of the north, and to every shower of snow and rain.

Having discussed what appeared necessary to be said upon relative beauty, singly considered, or in combination with intrinsic beauty, the next step is, to view architecture as one of the fine arts, and to examine those buildings and parts of buildings that are solely calculated to please the eye. In the works of nature, grand and magnificent, variety prevails. The timid hand of art, is guided by rule and compass. Hence it is, that in works which imitate nature, the great art is to hide every appearance of art; which is done by avoiding regularity and indulging variety. But in works of art that are original and not imitative, such as architecture, strict regularity and uniformity ought to be studied so far as consistent with utility.

In buildings intended to please the eye, proportion is not less essential than regularity and uniformity; for we are so framed by nature, as to be pleased equally with each of these. By many writers it is taken for granted, that in all the parts of a building there are certain strict proportions which please the eye; precisely as there are certain strict proportions of sound which please the ear; and that in both the slightest deviation is equally disagreeable. Others again seem to relish more a comparison betwixt proportion in numbers and proportion in quantity; and hold that the same proportions are agreeable in both. The proportions, for example, of the numbers 16, 24, and 36 are agreeable; and so, say they, are the proportions of a room, the height of which is 16 feet, the breadth 24, and the length 36. This point, with relation to the present subject, being of importance, the reader will examine it with attention and impartiality. To refute the notion of a resemblance betwixt musical proportions and those of architecture, it might be sufficient to observe in general, that the one is addressed to the ear, the other to the eye; and that objects of different senses have no resemblance, nor indeed any relation to each other. But more particularly, what pleases the ear in harmony, is not the proportion of the strings of the instrument, but of the sounds that these strings produce. In architecture, on the contrary, it is the proportion of different quantities that pleases the eye, without the least relation to sound. Beside, were quantity here to be the sole ground of comparison, we have no reason to presume, that there is any natural analogy betwixt the proportions that please in a building and the proportions of strings that produce concordant sounds. I instance in particular an octave, the most complete of all concords. An octave is produced by two strings of the same tension and diameter, and as to length in the proportion of one to two. I do not know, that this proportion will be agreeable in any two parts of a building. I add, that concordant notes are produced by wind instruments, which, as to proportion, appear not to have even the slightest resemblance to a building.

With respect to the other notion instituting a comparison betwixt proportion in numbers and proportion in quantity, I urge, that number and quantity are so distinct from each other, as to afford no probability of any natural relation betwixt them. Quantity is a real quality of every substance or body: number is not a real quality, but merely a conception that arises upon viewing a plurality of things in succession. Because an arithmetical proportion is agreeable in numbers, have we any reason to conclude that it must also be agreeable in quantity? At this rate, a geometrical proportion and many others, ought also to be agreeable in both. A certain proportion may coincide in both; and among an endless variety of proportions, it would be wonderful, if there never should be a coincidence. One example is given of this coincidence, in the numbers 16, 24, and 36; but to be convinced that it is merely accidental, we need but reflect, that the same proportions are not applicable to the external figure of a house, and far less to a column.

That we are framed by nature to relish proportion as well as regularity, is indisputable: but that agreeable proportion, like concord in sounds, is confined to certain precise measures, is not warranted by experience: on the contrary, we learn from experience, that various proportions are equally agreeable, that proportion is never tied down to precise measures but admits more and less, and that we are not sensible of disproportion till the difference betwixt the quantities compared become the most striking circumstance. Columns evidently admit different proportions, equally agreeable. The case is the same in houses, rooms, and other parts of a building. And this opens an interesting reflection. The foregoing difference betwixt concord and proportion, is an additional instance of that admirable harmony which subsists among the several branches of the human frame. The ear is an accurate judge of sounds and of their smallest differences; and that concord in sounds should be regulated by accurate measures, is perfectly well suited to this accuracy of perception. The eye is more uncertain about the size of a large object, than of one that is small; and in different situations the same object appears of different sizes. Delicacy of feeling therefore with respect to proportion in quantities, would be an useless quality. It is much better ordered, that there should be such a latitude with respect to agreeable proportions, as to correspond to the uncertainty of the eye with respect to quantity.

But this scene is too interesting to be passed over in a cursory view: all its beauties are not yet display’d. I proceed to observe, that to make the eye as delicate with respect to proportion as the ear is with respect to concord, would not only be an useless quality, but be the source of continual pain and uneasiness. I need go no farther for a proof than the very room I possess at present: every step I take, varies to me, in appearance, the proportion of the length and breadth. At that rate, I should not be happy but in one precise spot, where the proportion appears agreeable. Let me further observe, that it would be singular indeed, to find in the nature of man, any two principles in perpetual opposition to each other. This would precisely be the case, if proportion were circumscribed like concord; for it would exclude all but one of those proportions that utility requires in different buildings, and in different parts of the same building.

It is ludicrous to observe all writers acknowledging the necessity of accurate proportions, and yet differing widely about them. Laying aside reasoning and philosophy, one fact universally agreed on ought to have undeceived them, that the same proportions which please in a model are not agreeable in a large building. A room 48 feet in length and 24 in breadth and height, is well proportioned; but a room 12 feet wide and high and 24 long, looks like a gallery.
