§ XXIV. Not knowingly. I do not suppose a single hint was ever actually taken from mineral form; not even by the Arabs in their stalactite pendants and vaults: all that I mean to allege is, that beautiful ornament, wherever found, or however invented, is always either an intentional or unintentional copy of some constant natural form; and that in this particular instance, the pleasure we have in these geometrical figures of our own invention, is dependent for all its acuteness on the natural tendency impressed on us by our Creator to love the forms into which the earth He gave us to tread, and out of which He formed our bodies, knit itself as it was separated from the deep. § XXV. 3. Forms of Water (Waves). The reasons which prevent rocks from being used for ornament repress still more forcibly the portraiture of the sea. Yet the constant necessity of introducing some representation of water in order to explain the scene of events, or as a sacred symbol, has forced the sculptors of all ages to the invention of some type or letter for it, if not an actual imitation. We find every degree of conventionalism or of naturalism in these types, the earlier being, for the most part, thoughtful symbols; the latter, awkward attempts at portraiture.[65] The most conventional of all types is the Egyptian zigzag, preserved in the astronomical sign of Aquarius; but every nation, with any capacities of thought, has given, in some of its work, the same great definition of open water, as "an undulatory thing with fish in it." I say _open_ water, because inland nations have a totally different conception of the element. Imagine for an instant the different feelings of an husbandman whose hut is built by the Rhine or the Po, and who sees, day by day, the same giddy succession of silent power, the same opaque, thick, whirling, irresistible labyrinth of rushing lines and twisted eddies, coiling themselves into serpentine race by the reedy banks, in omne volubilis ævum,--and the image of the sea in the mind of the fisher upon the rocks of Ithaca, or by the Straits of Sicily, who sees how, day by day, the morning winds come coursing to the shore, every breath of them with a green wave rearing before it; clear, crisp, ringing, merry-minded waves, that fall over and over each other, laughing like children as they near the beach, and at last clash themselves all into dust of crystal over the dazzling sweeps of sand. Fancy the difference of the image of water in those two minds, and then compare the sculpture of the coiling eddies of the Tigris and its reedy branches in those slabs of Nineveh, with the crested curls of the Greek sea on the coins of Camerina or Tarentum. But both agree in the undulatory lines, either of the currents or the surface, and in the introduction of fish as explanatory of the meaning of those lines (so also the Egyptians in their frescoes, with most elaborate realisation of the fish). There is a
