which they carried through to the outermost zone, making a passage from the sea up to this, which became a harbor, and leaving an opening sufficient to enable the largest vessels to find ingress.  Moreover, they divided the zones of land which parted the zones of sea, constructing bridges of such a width as would leave a passage for a single trireme to pass out of one into another, and roofed them over; and there was a way underneath for the ships, for the banks of the zones were raised considerably above the water.  Now the largest of the zones into which a passage was cut from the sea was three stadia in breadth, and the zone of land which came next of equal breadth; but the next two, as well the zone of water as of land, were two stadia, and the one which surrounded the central island was a stadium only in width.  The island in which the palace was situated had a diameter of five stadia.  This, and the zones and the bridge, which was the sixth part of a stadium in width, they surrounded by a stone wall, on either side placing towers, and gates on the bridges where the sea passed in.  The stone which was used in the work they quarried from underneath the centre island and from underneath the zones, on the outer as well as the inner side.  One kind of stone was white, another black, and a third red; and, as they quarried, they at the same time hollowed out docks double within, having roofs formed out of the native rock.  Some of their buildings were simple, but in others they put together different stones, which they intermingled for the sake of ornament, to be a natural source of delight.  The entire circuit of the wall which went round the outermost one they covered with a coating of brass, and the circuit of the next wall they coated with tin, and the third, which encompassed the citadel flashed with the red light of orichalcum.  The palaces in the interior of the citadel were constructed in this wise:  In the centre was a holy temple dedicated to Cleito and Poseidon, which remained inaccessible, and was surrounded by an enclosure of gold; this was the spot in which they originally begat the race of the ten princes, and thither they annually brought the fruits of the earth in their season from all the ten portions, and performed sacrifices to each of them.  Here, too, was Poiseidon’s own temple, of a stadium in length and half a stadium in width, and of a proportionate height, having a sort of barbaric splendor.  All the outside of the temple, with the exception of the pinnacles, they covered with silver, and the pinnacles with gold.  In the interior of the temple the roof was of ivory, adorned everywhere with gold and silver and orichalcum; all the other parts of the walls and pillars and floor they lined with orichalcum.  In the temple they placed statues of gold:  there was the god himself standing in a chariot—­the charioteer of six winged horses—­and of such a size that he touched the roof of the building with his head; around him there were a hundred Nereids riding on dolphins, for
