I have said that the decoration of a building should be brought about by the employment of such ornament as was, in time past, associated with the particular form of architecture employed in the building to be decorated, if a precisely similar form of architecture previously existed. Let not the ornament, however, be a mere servile imitation of what has gone before, but let the designer study the ornament of bygone ages till he understands and feels its spirit, and then let him strive to produce new forms and new combinations in the spirit of the ornament of the past.
This must also be carefully noted—that the ornament of a particular period does not consist merely of the forms employed in the architecture, drawn in colour on the wall, or the ceiling, as the case may be. The particular form of ornament used in association with some forms of Gothic architecture was very different in character from what we might expect from the nature of the architecture itself, and did not to any extent consist of flatly-treated crockets, gable ends, trefoils, cinque-foils, etc. The ornament of the past must be studied in its purity, and not from those wretched attempts at the production of Gothic decoration which we often see.
In what we may call the typical English house of the present day there is really no architecture, and if such a building is to be decorated it is almost legitimate to employ any style of ornamentation. In such a case I should choose a style which has no very marked features—which is not strongly Greek, or strongly Gothic, or strongly Italian; and if there is the necessary ability, I should say try and produce ornaments having novelty of character, and yet showing your knowledge of the good qualities of all styles that are past. If this is attempted, care must be exercised in order to avoid getting a mere combination of elements from various styles as one ornament. Nothing can be worse than to see a bit of Greek, a fragment of Egyptian, an Alhambraic scroll, a Gothic flower, and an Italian husk associated together as one ornament; unless this were done advisedly and in order to meet a very special want, such an ornamental composition would be detestable. What I recommend is the production of new forms; but the new composition may have the vigour of the best Gothic ornament, the severity of Egyptian, the intricacy of the Persian, the gorgeousness of the Alhambra, and so on, only it must not imitate in detail the various styles of the past.
Now as to the decoration of a room. If one part only can be decorated, let that one part be the ceiling. Nothing appears to me more strange than that our ceilings, which can be properly seen, are usually white in middle-class houses, while the walls, which are always in part hidden, and even the floor, on which we tread, should have colour and pattern applied to them; and of this I am certain, that, considered from a decorative point of view, our ordinary treatment is wrong.
We glory in a clear blue sky overhead, and we speak of the sky as increasing in beauty as it becomes deeper and deeper in tint. Thus the depth of the tint of the Italian sky is familiar to us all. Why, then, make our ceilings white? I often ask this question, and am told that the whiteness renders the ceiling almost invisible; hence it is preferred. This idea is very absurd; first, because blue is the most ethereal and most distant of all colours [(see Chap. II., page 33)]; and, second, do we not build a house with the view of procuring shelter? hence why do we seek to realise the feeling that we are without a covering over our heads? We only like a white ceiling because we have been accustomed to such from infancy, and because we have been taught to regard a clean white ceiling as all that is to be desired. I knew a Yorkshire lady who, upon being asked by her husband whether she would like the drawing-room ceiling decorated, replied that she thought not, as she could not then have it re-whitewashed every year. The idea was clean certainly. Blue, I have said, is ethereal in character; it is so, and may become exceedingly so if of medium depth and of a grey hue; hence, if a mere atmospheric effect was sought, it would be desirable that this colour be used on the ceiling rather than white. But, as we have just said, invisibility of the ceiling is absurd, as it is our protection from the weather. Further, the ceiling may become an object of great beauty, and it can be seen as a whole. Why then neglect the opportunity of arranging a beautiful object when there is no reason to the contrary? We like a beautiful coloured vase, or, if we do not, we can have it whitewashed, or even dispense with it altogether. We like beautiful walls, or we would have them whitewashed also; indeed, we like our surroundings generally beautiful. Why not, then, have beautiful ceilings, especially as they can be seen complete, while the wall is in part hidden by furniture and pictures?
I will suppose that we have an ordinary room to deal with. First, take away the wretched plaster ornament in the centre of the ceiling, for it is sure to be bad. There is not one such ornament out of a thousand that can be so treated as to make the ceiling look as well as it would do without it. Now place all over the ceiling a flat painted or stencilled pattern, a pattern which repeats equally in all directions (as Fig. 51), and let this pattern be in blue (of any depth) and white, or in blue (of any depth) and cream-colour, and it is sure to look well (the blue being the ground, and the cream-colour or white the ornament).
Simple patterns in cream-colour on blue ground, but having a black outline, also look well (Fig. 52); and these might be prepared in paper, and hung on the ceiling as common paper-hangings, if cheapness is essential. Gold ornaments on a deep blue ground, with black outline, also look rich and effective. These are all, however, simple treatments, for any amount of colour may be used on a ceiling, provided the colours are employed in very small masses, and perfectly mingled, so that the effect produced is that of a rich coloured bloom [(see Chap. II., page 46)]. A ceiling should be beautiful, and should also be manifest; but if it must be somewhat indistinct, in order that the caprices of the ignorant be humoured, let the pattern be in middle-tint or pale blue and white only.
I like to see the ceiling of a room covered all over with a suitable pattern, but I do not at all object to a large central ornament only, or to a centre ornament and corners; especially if the cornice is heavy, so as to give compensating weight to the margin. I have recently designed and seen carried out one or two centre ornaments for drawing-rooms, which ornaments were twenty-one feet in diameter. A centre ornament, if properly treated, may be very large without looking heavy; it may, indeed, extend at least two-thirds of the way from the centre to the margin of the ceiling. I do not speak of plaster ornaments, but of flat decorations.
