Plato Critias 115

Moreover, it contained a very large stock of elephants; for there was an ample food-supply not only for all the other animals which haunt the marshes and lakes and rivers, 115a or the mountains or the plains, but likewise also for this animal, which of its nature is the largest and most voracious. And in addition to all this, it produced and brought to perfection all those sweet-scented stuffs which the earth produces now, whether made of roots or herbs or trees, or of liquid gums derived from flowers or fruits. The cultivated fruit ¹ also, and the dry, ² which serves us for nutriment, and all the other kinds that we use for our meals—the various species of which are comprehended under the name vegetables— 115b and all the produce of trees which affords liquid and solid food and unguents, ³ and the fruit of the orchard-trees, so hard to store, which is grown for the sake of amusement and pleasure, ⁴ and all the after-dinner fruits ⁵ that we serve up as welcome remedies for the sufferer from repletion,—all these that hallowed island, as it lay then beneath the sun, produced in marvellous beauty and endless abundance. And thus, receiving from the earth all these products, they furnished forth 115c their temples and royal dwellings, their harbors and their docks, and all the rest of their country, ordering all in the fashion following. ⁶
  First of all they bridged over the circles of sea which surrounded the ancient metropolis, making thereby a road towards and from the royal palace. And they had built the palace at the very beginning where the settlement was first made by their God ⁷ and their ancestors; and as each king received it from his predecessor, he added to its adornment 115d and did all he could to surpass the king before him, until finally they made of it an abode amazing to behold for the magnitude and beauty of its workmanship. For, beginning at the sea, they bored a channel right through to the outermost circle, which was three plethra in breadth, one hundred feet in depth, and fifty stades ⁸ in length; and thus they made the entrance to it from the sea like that to a harbor by opening out a mouth large enough for the greatest ships to sail through. ⁹ Moreover, through the circles of land, 115e which divided those of sea, over against the bridges they opened out a channel leading from circle to circle, large enough to give passage to a single trireme; and this they roofed over above so that the sea-way was subterranean; for the lips of the landcircles were raised a sufficient height above the level of the sea. The greatest of the circles into which a boring was made for the sea was three stades in breadth, and the circle of land next to it was of equal breadth; and of the second pair of circles that of water was two stades in breadth and that of dry land equal again to the preceding one of water; and the circle which ran round the central island itself was of a stade's breadth.
