examined that while we have traced the limits of license, we have not fixed those of that high rectitude which refuses license. It is thus true that there is no falsity, and much beauty, in the use of external colour, and that it is lawful to paint either pictures or patterns on whatever surfaces may seem to need enrichment. But it is not less true, that such practices are essentially unarchitectural; and while we cannot say that there is actual danger in an over use of them, seeing that they have been always used most lavishly in the times of most noble art, yet they divide the work into two parts and kinds, one of less durability than the other, which dies away from it in process of ages, and leaves it, unless it have noble qualities of its own, naked and bare. That enduring noblesse I should, therefore, call truly architectural; and it is not until this has been secured, that the accessory power of painting may be called in, for the delight of the immediate time; nor this, as I think, until every resource of a more stable kind has been exhausted. The true colours of architecture are those of natural stone, and I would fain see these taken advantage of to the full. Every variety of hue, from pale yellow to purple, passing through orange, red and brown, is entirely at our command; nearly every kind of green and grey is also attainable; and with these, and pure white, what harmonies might we not achieve? Of stained and variegated stone, the quantity is unlimited, the kinds innumerable; where brighter colours are required, let glass, and gold protected by glass, be used in mosaic—a kind of work as durable as the solid stone, and incapable of losing its lustre by time=and let the painter's work be reserved for the shadowed loggia and inner chamber. This is the true and faithful way of building; where this cannot be, the device of external colouring may, indeed, be employed without dishonour; but it must be with the warning reflection, that a time will come when such aids must pass away, and when the building will be judged
