31. Archimedes, the well-known inventor, was by birth a Syracusan. Now this old geometrician, who had passed through seventy-five seasons, had built many powerful engines, and by the triple pulley, with the aid of the left hand alone, could launch a merchant ship of fifty thousand medimni burden. And when Marcellus once, the Roman general, assaulted Syracuse by land and sea, this man first by his engines drew up some merchantmen, and lifting them up against the wall of Syracuse dropped them again and sent them every one to the bottom, crews and all. Again, as Marcellus removed his ships a little distance, the old man gave all the Syracusans the power to lift stones of a wagon's size, and letting them go one by one to sink the ships. When Marcellus withdrew a bow shot thence, the old man manufactured a kind of hexagonal mirror, and at an interval proportionate to the size of the mirror he set similar small mirrors with four edges, moving by links and by a kind of hinge, and made the glass the center of the rays of the sun,--its noontide ray, whether in summer or in the dead of winter. So after that when the beams were reflected into this, a terrible kindling of flame arose upon the ships, and he reduced them to ashes a bowshot off. Thus by his contrivances did the old man vanquish Marcellus. He used to say, moreover, in Dorian, the Syracusan dialect: "Give me where to stand, and with a lever I will move the whole earth." This man, when (according to Diodorus) this Syracuse surrendered herself entire to Marcellus, or (according to Dio) was pillaged by the Romans during an all-night festival to Artemis that the citizens were celebrating, was killed by a certain Roman in the following fashion.--He was bent over, drawing some geometrical figure, and some Roman, coming upon him, made him his prisoner and began to drag him away: but he, with all his attention fixed just then upon his figure, not knowing who it was that pulled him said to the man: "Stand aside, fellow, from my figure." But as the other kept on dragging, he turned, and recognizing him as a Roman cried out: "Let some one give me one of my machines." The Roman in terror immediately killed him, an unsound weak old man, but marvelous through his works. Marcellus straightaway mourned on learning this, buried him brilliantly in his ancestral tomb, assisted by the noblest citizens and all the Romans, and the man's murderer, I trow, he slew with an axe. Dio and Diodorus have written the story. (Tzetzes, Hist. 2, 103-149. Cp. Zonaras, 9, 4.) 32. Proculus sings of having forged fire-producing mirrors and of having hung them from the wall opposite the enemy's ships. Then when the rays of the sun fell upon these, fire was struck out of them that consumed the naval force of the opponents and the ships themselves,--a device which Dio relates Archimedes hit upon long ago, at the time when the Romans were besieging Syracuse. (Zonaras, 14, 3.)
