sort of framework, which they say was erected and made out of the wood of fifty ships of five ranks of oars; and it was launched by the multitude with great acclamations and blowing of trumpets. But after that a Phœnician devised a new method of launching it, having dug a trench under it, equal to the ship itself in length, which he dug close to the harbour. And in the trench he built props of solid stone five cubits deep, and across them he laid beams crosswise, running the whole width of the trench, at four cubits' distance from one another; and then making a channel from the sea he filled all the space which he had excavated with water, out of which he easily brought the ship by the aid of whatever men happened to be at hand; then closing the entrance which had been originally made, he drained the water off again by means of engines; and when this had been done the vessel rested securely on the before-mentioned cross-beams. 38. "Philopator also built a vessel for the river which he called Thalamegus, or the Carrier of his Bed-chamber, in length half a stadium, and in width at the broadest part thirty cubits; and the height together with the frame for the awning was little short of forty cubits. And its appearance was not exactly like ships of war, nor merchant vessels either, but it was something different from both, on account of the necessity imposed by the depth of the river. For below it was flat and broad; but in its main hull it was high. And the parts at the extremity, and especially at the head, extended a sufficient length, so as to exhibit a very pretty and elegant sweep. This ship also had two heads and two sterns. And it rose to a considerable height above the water, as was necessary, because the waves in the river often rise very high. And in the middle of its hull were constructed banqueting-rooms and sleeping-rooms, and everything else which may be convenient for living in. And round the ship were double corridors running about three sides, each of which was not less than five plethra in circumference. And the arrangement of the lower one was like a peristyle, and that in the upper part was covered in, and surrounded with walls and windows on all sides. And when you first came into the vessel by the stern your eye was met by a colonnade, open in front, and surrounded by pillars. And opposite to it in the bow of the vessel there was a sort of propylæum constructed, made of ivory and most expensive woods. And after you had passed through that, then you came to something like a proscenium, covered in overhead. And again in the same way in the middle of the vessel was another colonnade, open behind, and an entrance of four folding-doors led to it. And both on the right hand and on the left there were windows, admitting a pleasant breeze.
