The people of Rome chose Fabius and Marcellus consuls. Hannibal was then traveling about in what is called Calabria and in adjacent regions, and they assigned the care of him to Gracchus, who had held office before them. The latter routed Hanno (who had come from Bruttium and confronted him near Beneventum), and then going on he watched Hannibal closely, kept ravaging the possessions of rebels and won some cities safely back. The consuls themselves turned their steps toward Campania, for they were anxious to subdue it and so leave no element of hostility behind their backs when they should march against Hannibal. They then divided forces. Fabius overran the districts of Campania and Samnium. Marcellus crossed into Sicily and proceeded to besiege Syracuse. The town had submitted to him, but then had revolted again through the treachery of some men by the use of a false message. He would have subdued it very speedily,--for he assaulted the wall by both land and sea at once,--had not Archimedes with his inventions enabled the citizens to resist an extremely long time. By his devices he suspended stones and heavy-armed soldiers in the air whom he would let down suddenly and soon draw up again. Even ships that carried towers he would dash one upon another; he would pull them up and [Sidenote: (FRAG. 56^31?)] LIFTING THEM HIGH WOULD LET GO ALL IN A MASS so that when they fell into the water they were sunk by the impact. At last in an incredible manner he destroyed the whole Roman fleet by conflagration. By tilting a kind of mirror toward the sun he concentrated the sun's beams on it; and as the thickness and smoothness of the mirror cooeperated to ignite the air from these beams he kindled a great flame, all of which he directed upon the ships that lay at anchor in the path of the fire, and he consumed them all. Marcellus, therefore, despairing of capturing the city on account of the inventiveness of Archimedes thought to take it by famine after a regular investment. This duty he assigned to Pulcher while he himself turned his attention to those who had participated in the revolt of Syracuse. Any who yielded were granted pardon, but those who resisted he treated harshly, and he captured a number of the cities by force, some also by betrayal. In the meantime Himilco had come from Carthage with an army, had occupied Agrigentum and Heraclea and had reached Syracuse. There he was first defeated, then was in turn victorious, and finally was beaten by a sudden assault on the part of Marcellus.
