It is by no means necessary for the sides of these pilasters, or the bounding lines of the bands containing inscriptions, to be kept straight; they may be varied at pleasure, so long as they are kept symmetrical in corresponding parts, and uniformly filled up with foliation emanating from, or connected with, the illuminated letters. Agreeable results may be produced by variations of such arrangements as the one suggested. Frequently round doors, windows, fireplaces, &c., inscriptions may be executed with very good effect, either on label-scrolls or simple borders, and with greater or less brilliancy of colour, according to the circumstances of the case. Often simplicity and quiet have greater charms than glitter or brilliancy; thus black and red, on a light-coloured ground, the most primitive combination in the history of writing, is always sure to produce an agreeable impression: blue, crimson, or marone on gold, or _vice versâ_, are no less safe: black, white, and gold, counterchanged, can hardly go wrong. Few amateurs will be likely to attempt illuminations upon plaster ceilings, owing to the great difficulty they will experience in working overhead with a steady hand. They will generally do wisely--to execute the principal portions on paper, tracing-paper, or canvas,--to fasten them up, as will be hereafter directed,--and to confine the decoration actually painted on the ceiling, to a few panels, lines, or plain bands of colour, which may be readily executed by any clever house-painter or grainer, even if altogether ignorant of drawing and the art of design. The most beautiful illuminated ceiling of mediæval times I believe to be that of the chapel in the celebrated Jacques Coeur's house, at Bourges, in France. It is vaulted, and each compartment contains inscribed labels held by floating angels. The white draperies of the angels are relieved on a delicate blue ground only, so that the stronger contrast of the black writing on the white labels gives a marked predominance to the inscriptions; which, being arranged symmetrically, produce in combination agreeable geometrical figures.
