For the success of Hannibal had excited the Carthaginians to lay claim to that whole island; chiefly because, after the murder of the tyrant Hieronymus, all things had been in tumult and confusion at Syracuse. For which reason the Romans also had sent before to that city a force under the conduct of Appius, as praetor. While Marcellus was receiving that army, a number of Roman soldiers cast themselves at his feet, upon occasion of the following calamity. Of those that survived the battle at Cannae, some had escaped by flight, and some were taken alive by the enemy; so great a multitude, that it was thought there were not remaining Romans enough to defend the wall of the city. And yet the magnanimity and constancy of the city was such, that it would not redeem the captives from Hannibal, though it might have done so for a small ransom; a decree of the senate forbade it, and chose rather to leave them to be killed by the enemy, or sold out of Italy; and commanded that all who had saved themselves by flight should be transported into Sicily, and not permitted to return into Italy, until the war with Hannibal should be ended. These, therefore, when Marcellus was arrived in Sicily, addressed themselves to him in great numbers; and casting themselves at his feet, with much lamentation and tears humbly besought him to admit them to honourable service; and promised to make it appear by their future fidelity and exertions that that defeat had been received rather by misfortune than by cowardice. Marcellus, pitying them, petitioned the senate by letters, that he might have leave at all times to recruit his legions out of them. After much debate about the thing, the senate decreed they were of opinion that the commonwealth did not require the service of cowardly soldiers;if Marcellus perhaps thought otherwise, he might make use of them, provided no one of them be honoured on any occasion with a crown or military gift, as a reward of his virtue or courage. This decree stung Marcellus; and on his return to Rome, after the Sicilian war was ended, he upbraided the senate that they had denied to him, who had so highly deserved of the republic, liberty to relieve so great a number of citizens in great calamity.
At this time Marcellus, first incensed by injuries done him by Hippocrates, commander of the Syracusans (who, to give proof of his good affection to the Carthaginians, and to acquire the tyranny to himself, had killed a number of Romans at Leontini), besieged and took by force the city of Leontini; yet violated none of the townsmen; only deserters, as many as he took, he subjected to the punishment of the rods and axe. But Hippocrates, sending a report to Syracuse, that Marcellus had put all the ***** population to the sword, and then coming upon the Syracusans, who had risen in tumult upon that false report, made himself master of the city. Upon this Marcellus moved with his whole army to Syracuse, and encamping near the wall, sent ambassadors into the city to relate to the Syracusans the truth of what had been done in Leontini. When these could not prevail by treaty, the whole power being now in the hands of Hippocrates, he proceeded to attack the city both by land and by sea. The land forces were conducted by Appius: Marcellus, with sixty galleys, each with five rows of oars, furnished with all sorts of arms and missiles, and a huge bridge of planks laid upon eight ships chained together, upon which was carried the engine to cast stones and darts, assaulted the walls, relying on the abundance and magnificence of his preparations, and on his own previous glory; all which, however, were, it would seem, but trifles for Archimedes and his machines.
These machines he had designed and contrived, not as matters of any importance, but as mere amusements in geometry; in compliance with King Hiero's desire and request, some little time before, that he should reduce to practice some part of his admirable speculation in science, and by accommodating the theoretic truth to sensation and ordinary use, bring it more within the appreciation of the people in general. Eudoxus and Archytas had been the first originators of this far-famed and highly-prized art of mechanics, which they employed as an elegant illustration of geometrical truths, and as means of sustaining experimentally, to the satisfaction of the senses, conclusions too intricate for proof by words and diagrams. As, for example, to solve the problem, so often required in constructing geometrical figures, given the two extremes, to find the two mean lines of a proportion, both these mathematicians had recourse to the aid of instruments, adapting to their purpose certain curves and sections of lines. But what with Plato's indignation at it, and his invectives against it as the mere corruption and annihilation of the one good of geometry, which was thus shamefully turning its back upon the unembodied objects of pure intelligence to recur to sensation, and to ask help (not to be obtained without base supervisions and depravation) from matter; so it was that mechanics came to be separated from geometry, and, repudiated and neglected by philosophers, took its place as a military art. Archimedes, however, in writing to King Hiero, whose friend and near relation he was, had stated that given the force, any given weight might be moved, and even boasted, we are told, relying on the strength of demonstration, that if there were another earth, by going into it he could remove this.
