XV. So, then, these are the two virtues of building: first, the signs of man’s own good work; secondly, the expression of man’s delight in better work than his own. And these are the two virtues of which I desire my reader to be able quickly to judge, at least in some measure; to have a definite opinion up to a certain point. Beyond a certain point he cannot form one. When the science of the building is great, great science is of course required to comprehend it; and, therefore, of difficult bridges, and light-houses, and harbor walls, and river dykes, and railway tunnels, no judgment may be rapidly formed. But of common buildings, built in common circumstances, it is very possible for every man, or woman, or child, to form judgment both rational and rapid. Their necessary, or even possible, features are but few; the laws of their construction are as simple as they are interesting. The labor of a few hours is enough to render the reader master of their main points; and from that moment he will find in himself a power of judgment which can neither be escaped nor deceived, and discover subjects of interest where everything before had appeared barren. For though the laws are few and simple, the modes of obedience to them are not so. Every building presents its own requirements and difficulties; and every good building has peculiar appliances or contrivances to meet them. Understand the laws of structure, and you will feel the special difficulty in every new building which you approach; and you will know also, or feel instinctively,32 whether it has been wisely met or otherwise. And an enormous number of buildings, and of styles of buildings, you will be able to cast aside at once, as at variance with these constant laws of structure, and therefore unnatural and monstrous.
§ XVI. Then, as regards decoration, I want you only to consult your own natural choice and liking. There is a right and wrong in it; but you will assuredly like the right if you suffer your natural instinct to lead you. Half the evil in this world comes from people not knowing what they do like, not deliberately setting themselves to find out what they really enjoy. All people enjoy giving away money, for instance: they don’t know that,—they rather think they like keeping it; and they do keep it under this false impression, often to their great discomfort. Every body likes to do good; but not one in a hundred finds this out. Multitudes think they like to do evil; yet no man ever really enjoyed doing evil since God made the world.
So in this lesser matter of ornament. It needs some little care to try experiments upon yourself: it needs deliberate question and upright answer. But there is no difficulty to be overcome, no abstruse reasoning to be gone into; only a little watchfulness needed, and thoughtfulness, and so much honesty as will enable you to confess to yourself and to all men, that you enjoy things, though great authorities say you should not.
§ XVII. This looks somewhat like pride; but it is true humility, a trust that you have been so created as to enjoy what is fitting for you, and a willingness to be pleased, as it was intended you should be. It is the child’s spirit, which we are then most happy when we most recover; only wiser than children in that we are ready to think it subject of thankfulness that we can still be pleased with a fair color or a dancing light. And, above all, do not try to make all these pleasures reasonable, nor to connect the delight which you take in ornament with that which you take in construction or usefulness. They have no connection; and every effort that you make to reason from one to the other will blunt your sense of beauty, or confuse it with sensations altogether inferior to it. You were made for enjoyment, and the world was filled with things which you will enjoy, unless you are too proud to be pleased by them, or too grasping to care for what you cannot turn to other account than mere delight. Remember that the most beautiful things in the world are the most useless; peacocks and lilies for instance; at least I suppose this quill I hold in my hand writes better than a peacock’s would, and the peasants of Vevay, whose fields in spring time are as white with lilies as the Dent du Midi is with its snow, told me the hay was none the better for them.
§ XVIII. Our task therefore divides itself into two branches, and these I shall follow in succession. I shall first consider the construction of buildings, dividing them into their really necessary members or features; and I shall endeavor so to lead the reader forward from the foundation upwards, as that he may find out for himself the best way of doing everything, and having so discovered it, never forget it. I shall give him stones, and bricks, and straw, chisels, and trowels, and the ground, and then ask him to build; only helping him, as I can, if I find him puzzled. And when he has built his house or church, I shall ask him to ornament it, and leave it to him to choose the ornaments as I did to find out the construction: I shall use no influence with him whatever, except to counteract previous prejudices, and leave him, as far as may be, free. And when he has thus found out how to build, and chosen his forms of decoration, I shall do what I can to confirm his confidence in what he has done. I shall assure him that no one in the world could, so far, have done better, and require him to condemn, as futile or fallacious, whatever has no resemblance to his own performances.
CHAPTER III.
THE SIX DIVISIONS OF ARCHITECTURE
§ I. The practical duties of buildings are twofold.
They have either (1), to hold and protect something; or (2), to place or carry something.
1. Architecture of Protection. This is architecture intended to protect men or their possessions from violence of any kind, whether of men or of the elements. It will include all churches, houses, and treasuries; fortresses, fences, and ramparts; the architecture of the hut and sheepfold; of the palace and the citadel: of the dyke, breakwater, and sea-wall. And the protection, when of living creatures, is to be understood as including commodiousness and comfort of habitation, wherever these are possible under the given circumstances.
2. Architecture of Position. This is architecture intended to carry men or things to some certain places, or to hold them there. This will include all bridges, aqueducts, and road architecture; light-houses, which have to hold light in appointed places; chimneys to carry smoke or direct currents of air; staircases; towers, which are to be watched from or cried from, as in mosques, or to hold bells, or to place men in positions of offence, as ancient moveable attacking towers, and most fortress towers.
§ II. Protective architecture has to do one or all of three things: to wall a space, to roof it, and to give access to it, of persons, light, and air; and it is therefore to be considered under the three divisions of walls, roofs, and apertures.
We will take, first, a short, general view of the connection of these members, and then examine them in detail: endeavoring always to keep the simplicity of our first arrangement in view; for protective architecture has indeed no other members than these, unless flooring and paving be considered architecture, which it is only when the flooring is also a roof; the laying of the stones or timbers for footing being pavior’s or carpenter’s work, rather than architect’s; and, at all events, work respecting the well or ill doing of which we shall hardly find much difference of opinion, except in points of æsthetics. We shall therefore concern ourselves only with the construction of walls, roofs, and apertures.
§ III. 1. Walls.—A wall is an even and united fence, whether of wood, earth, stone, or metal. When meant for purposes of mere partition or enclosure, it remains a wall proper: but it has generally also to sustain a certain vertical or lateral pressure, for which its strength is at first increased by some general addition to its thickness; but if the pressure becomes very great, it is gathered up into piers to resist vertical pressure, and supported by buttresses to resist lateral pressure.
If its functions of partition or enclosure are continued, together with that of resisting vertical pressure, it remains as a wall veil between the piers into which it has been partly gathered; but if it is required only to resist the vertical or roof pressure, it is gathered up into piers altogether, loses its wall character, and becomes a group or line of piers.
On the other hand, if the lateral pressure be slight, it may retain its character of a wall, being supported against the pressure by buttresses at intervals; but if the lateral pressure be very great, it is supported against such pressure by a continuous buttress, loses its wall character, and becomes a dyke or rampart.
§ IV. We shall have therefore (A) first to get a general idea of a wall, and of right construction of walls; then (B) to see how this wall is gathered into piers; and to get a general idea
