yet never losing the unity of its illumined swell and shadowy decline; and the head of every mighty tree, rich with tracery of leaf and bough, yet terminated against the sky by a true line, and rounded by a green horizon, which, multiplied in the distant forest, makes it look bossy from above; all these mark, for a great and honoured law, that diffusion od light for which the Byzantine ornaments were designed; and show us that those builders had truer sympathy with what God made majestic, than the self-contemplating and self-contented Greek. I know that they are barbaric in comparison; but there is a power in their barbarism of sterner tone, a power not sophistic nor penetrative, but embracing and mysterious; a power faithful more than thoughtful, which conceived and felt more than it created; a power that neither comprehended nor ruled itself, but worked and wandered as it listed, like mountain streams and winds; and which could not rest in the expression or seizure of finite form. It could not bury itself in acanthus leaves. Its imagery was taken from the shadows of the storms and hills, and had fellowship with the night and day of the earth itself.
XVI. I have endeavoured to give some idea of one of the hollow balls of stone which, surrounded by flowing leafage, occur in varied succession on the architrave of the central gate of St Mark's at Venice, in Plate I, fig. 3.

It would be difficult, as I think, to invent any thing more noble:
