but still in a system non-concurrent with their forms.
On the opposite side of this scale, ascending from the colour pattern, I would place the various forms of painting which may be associated with architecture: primarily, and as most fit for such purpose, the mosaic, highly abstract in treatment, and introducing brilliant colour in masses; the Madonna of Torcello being, as I think, the noblest type of the manner, and the Baptistery of Parma the richest: next, the purely decorative fresco, like that of the Arena Chapel; finally, the fresco becoming principal, as in the Vatican and Sistine. But I cannot, with any safety, follow the principles of abstraction in this pictorial ornament; since the noblest examples of it appear to me to owe their architectural applicability to their archaic manner; and I think that the abstraction and admirable simplicity which render them fit media of the most splendid colouring, cannot be recovered by a voluntary condescension.
