The height of the walls did not deter Sylla. He employed all sorts of engines in battering them, and made continual assaults. He spared neither danger, attacks, nor expense, to hasten the conclusion of the war. Without enumerating the rest of the warlike stores and equipage, twenty thousand mules were perpetually employed in working the machines only. Wood happening to fall short, from the great consumption made of it in the machines, which were often either broken or spoiled by the vast weight they carried, or burned by the enemy, he did not spare the sacred groves. He cut down the trees in the walks of the Academy and Lycæum, which were the finest and best planted in the suburbs, and caused the high walls that joined the port to the city to be demolished, in order to make use of the ruins in erecting his works, and carrying on his operations. Notwithstanding all disadvantages, the Athenians defended themselves like lions. They found means either to burn most of the machines erected against the walls, or by undermining them, to throw them down and break them to pieces. The Romans, on their side, behaved with no less vigour. Sylla, discouraged by so obstinate a defence, resolved to attack the Piræus no longer, and confined himself to reduce the place by famine. The city was now at the last extremity; a bushel of barley having been sold in it for a thousand drachms (about 25_l._ sterling). In the midst of the public misery, the governor, who was a lieutenant of Mithridates, passed his days and nights in debauch. The senators and priests went to throw themselves at his feet, conjuring him to have pity on the city, and to obtain a capitulation from Sylla; he dispersed them with arrow-shot, and in that manner drove them from his presence. He did not demand a cessation of arms, nor send deputies to Sylla, till reduced to the last extremity. As those deputies made no proposals, and asked nothing of him to the purpose, but ran on in praising and extolling Theseus, Eumolpus, and the exploits of the Athenians against the Medes, Sylla was tired of their discourse, and interrupted them by saying,--"Gentlemen haranguers, you may go back again, and keep your rhetorical flourishes to yourselves. For my part, I was not sent to Athens to be informed of your ancient prowess, but to chastise your modern revolt."
