It was by very slow advances that the ancients arrived at that high degree of excellence in the art of ship-building, which, in the most flourishing ages of Greece, its maritime states exhibited. In the Homeric age, the largest vessels known were of very moderate burden, since even the poet, who would doubtless allow himself some licence, speaks of no transport which could carry more than one hundred and fifty men. These barks, too, Thucydides thinks, were undecked, like the pirate vessels of his own times, and indeed in ours also, in most parts of the Ægæan, though I have myself sailed in a large Greek brig, of piratical construction, which carried several guns, and was not only decked, but so admirably built, that after labouring ten days in a storm, she made not an inch more water than when in port. The various stages in improvement have not been marked. They went on, however, each age excelling that which had preceded it, until at length having reached the utmost perfection of which their system was susceptible, they began to apply their skill to the creation of huge fabrics merely for show and magnificence, and calculated rather for the gratification of an insane luxury than for the genuine purposes of trade. One of these naval monsters was constructed at Syracuse under the eye of Archimedes, and at the expense of king Hiero. Having procured from the forests of Mount Ætna timber sufficient for the building of sixty triremes, together with a variety of other materials from Italy, Spain, and Gaul, as crooked timber for ribs, hard wood for pegs, with pitch and hemp, and Spanish broom[1683] for cables, he assembled a sufficient number of ship-wrights, with Archias, the Corinthian, at their head, and set them to work under the inspection of Archimedes, though he himself spent the greater part of his day overlooking the workmen at the dock. When in about six months the planking had been carried to about half the height of the hull, and properly sheathed with lead in lieu of the copper at present employed, the ship was launched[1684] by means of a machine, invented for the purpose by Archimedes, into a sort of floating dock, where it was completed in other six months. The planks were fastened to the ribs with copper bolts, of which some were of ten and others fifteen pounds’ weight, passed through holes prepared for them by the auger; and over the heads of these bolts plates of lead were fixed, having been first lined, as it were, with a layer of wadding steeped in pitch. ----- Footnote 1683: Athen. v. 40.
