From: The History of Rome, by Theodor Mommsen
Translated with the sanction of the author by William Purdie Dickson
But the object was attained. Hannibal encamped at Fiesole, while Gaius Flaminius was still waiting at Arezzo until the roads should become passable that he might blockade them. After the Roman defensive position had thus been turned, the best course for the consul, who might perhaps have been strong enough to defend the mountain passes but certainly was unable now to face Hannibal in the open field, would have been to wait till the second army, which had now become completely superfluous at Ariminum, should arrive. He himself, however, judged otherwise.
He was a political party leader, raised to distinction by his efforts to limit the power of the senate; indignant at the government in consequence of the aristocratic intrigues concocted against him during his consulship; carried away, through a doubtless justifiable opposition to their beaten track of partisanship, into a scornful defiance of tradition and custom; intoxicated at once by blind love of the common people and equally bitter hatred of the party of the nobles; and, in addition to all this, possessed with the fixed idea that he was a military genius.
