will remember that in Chap. VII. § V. it was said that the cornice of the wall, being cut to pieces and gathered together, formed the capital of the column. We have now to follow it in its transformation.
We must, of course, take our simplest form or root of cornices (a, in Fig. V., above). We will take X and Y there, and we must necessarily gather them together as we did Xb and Yb in Chap. VII. Look back to the tenth paragraph of Chap. VII., read or glance it over again, substitute X and Y for Xb and Yb, read capital for base, and, as we said that the capital was the hand of the pillar, while the base was its foot, read also fingers for toes; and as you look to the plate, Fig. XII., turn it upside down. Then h, in Fig. XII., becomes now your best general form of block capital, as before of block base.
§ II. You will thus have a perfect idea of the analogies between base and capital; our farther inquiry is into their differences. You cannot but have noticed that when Fig. XII. is turned upside down, the square stone (Y) looks too heavy for the supporting stone (X); and that in the profile of cornice (a of Fig. V.) the proportions are altogether different. You will feel the fitness of this in an instant when you consider that the principal function of the sloping part in Fig. XII. is as a prop to the pillar to keep it from slipping aside; but the function of the sloping stone in the cornice and capital is to carry weight above. The thrust of the slope in the one case should therefore be lateral, in the other upwards.
§ III. We will, therefore, take the two figures, e and h of Fig. XII., and make this change in them as we reverse them, using now the exact profile of the cornice a,—the father of cornices; and we shall thus have a and b, Fig. XIX.
Fig. XIX.
Both of these are sufficiently ugly, the reader thinks; so do I; but we will mend them before we have done with them: that at a is assuredly the ugliest,—like a tile on a flower-pot. It is, nevertheless, the father of capitals; being the simplest condition of the gathered father of cornices. But it is to be observed that the diameter of the shaft here is arbitrarily assumed to be small, in order more clearly to show the general relations of the sloping stone to the shaft and upper stone; and this smallness of the shaft diameter is inconsistent with the serviceableness and beauty of the arrangement at a, if it were to be realised (as we shall see presently); but it is not inconsistent with its central character, as the representative of every species of possible capital; nor is its tile and flower-pot look to be regretted, as it may remind the reader of the reported origin of the Corinthian capital. The stones of the cornice, hitherto called X and Y, receive, now that they form the capital, each a separate name; the sloping stone is called the Bell of the capital, and that laid above it, the Abacus. Abacus means a board or tile: I wish there were an English word for it, but I fear there is no substitution possible, the term having been long fixed, and the reader will find it convenient to familiarise himself with the Latin one.
§ IV. The form of base, e of Fig. XII., which corresponds to this first form of capital, a, was said to be objectionable only because it looked insecure; and the spurs were added as a kind of pledge of stability to the eye. But evidently the projecting corners of the abacus at a, Fig. XIX., are actually insecure; they may break off, if great weight be laid upon them. This is the chief reason of the ugliness of the form; and the spurs in b are now no mere pledges of apparent stability, but have very serious practical use in supporting the angle of the abacus. If, even with the added spur, the support seems insufficient, we may fill up the crannies between the spurs and the bell, and we have the form c.
