The same general principles of composition suggested for the treatment of walls may be applied to ceiling-decoration. Thus it is essential that where there is a division of parts, one part shall perceptibly predominate; and this, in a ceiling, should be the central division. The chief defect of the coffered Renaissance ceiling is the lack of this predominating part. Great as may have been the decorative skill expended on the treatment of beams and panels, the coffered ceiling of equal-sized divisions seems to press down upon the spectator's head; whereas the large central panel gives an idea of height that the great ceiling-painters were quick to enhance by glimpses of cloud and sky, or some aerial effect, as in Mantegna's incomparable ceiling of the Sala degli Sposi in the ducal palace of Mantua.
CEILING OF THE SALA DEGLI SPOSI, DUCAL PALACE, MANTUA.

PLATE XXV.
Ceiling-decoration should never be a literal reproduction of wall-decoration. The different angle and greater distance at which ceilings are viewed demand a quite different treatment and it is to the disregard of this fact that most badly designed ceilings owe their origin. Even in the high days of art there was a tendency on the part of some decorators to confound the two plane surfaces of wall and ceiling, and one might cite many wall-designs which have been transferred to the ceiling without being rearranged to fit their new position. Instances of this kind have never been so general as in the present day. The reaction from the badly designed mouldings and fungoid growths that characterized the ceilings of forty years ago has led to the use of attenuated laurel-wreaths combined with other puny attributes taken from Sheraton cabinets and Adam mantel-pieces. These so-called ornaments, always somewhat lacking in character, become absolutely futile when viewed from below.
This pressed-flower ornamentation is a direct precedent to the modern ceiling covered with wall-paper. One would think that the inappropriateness of this treatment was obvious; but since it has become popular enough to warrant the manufacture of specially designed ceiling-papers, some protest should be made. The necessity for hiding cracks in the plaster is the reason most often given for papering ceilings; but the cost of mending cracks is small and a plaster ceiling lasts much longer than is generally thought. It need never be taken down unless it is actually falling; and as well-made repairs strengthen and improve the entire surface, a much-mended ceiling is stronger than one that is just beginning to crack. If the cost of repairing must be avoided, a smooth white lining-paper should be chosen in place of one of the showy and vulgar papers which serve only to attract attention.
Of all forms of ceiling adornment painting is the most beautiful. Italy, which contains the three perfect ceilings of the world—those of Mantegna in the ducal palace of Mantua (see [Plate XXV]), of Perugino in the Sala del Cambio at Perugia and of Araldi in the Convent of St. Paul at Parma—is the best field for the study of this branch of art. From the semi-classical vaults of the fifteenth century, with their Roman arabesques and fruit-garlands framing human figures detached as mere ornament against a background of solid color, to the massive goddesses and broad Virgilian landscapes of the Carracci and to the piled-up perspectives of Giordano's school of prestidigitators, culminating in the great Tiepolo, Italian art affords examples of every temperament applied to the solution of one of the most interesting problems in decoration.
Such ceilings as those on which Raphael and Giovanni da Udine worked together, combining painted arabesques and medallions with stucco reliefs, are admirably suited to small low-studded rooms and might well be imitated by painters incapable of higher things.
There is but one danger in adapting this decoration to modern use—that is, the temptation to sacrifice scale and general composition to the search after refinement of detail. It cannot be denied that some of the decorations of the school of Giovanni da Udine are open to this criticism. The ornamentation of the great loggia of the Villa Madama is unquestionably out of scale with the dimensions of the structure. Much exquisite detail is lost in looking up past the great piers and the springing of the massive arches to the lace-work that adorns the vaulting. In this case the composition is less at fault than the scale: the decorations of the semi-domes at the Villa Madama, if transferred to a small mezzanin room, would be found to "compose" perfectly. Charming examples of the use of this style in small apartments may be studied in the rooms of the Casino del Grotto, near Mantua.
