Fabius Maximus (2.4-2.5)

The consul, Gaius Flaminius, was daunted by none of these things, for he was a man of a fiery and ambitious nature, and besides, he was elated by great successes which he had won before this, in a manner contrary to all expectation. He had, namely, although the senate dissented from his plan, and his colleague violently opposed it, joined battle with the Gauls and defeated them. Fabius also was less disturbed by the signs and portents, because he thought it would be absurd, although they had great effect upon many.

But when he learned how few in number the enemy were, and how great was their lack of resources, he exhorted the Romans to bide their time, and not to give battle to a man who wielded an army trained by many contests for this very issue, but to send aid to their allies, to keep their subject cities well in hand, and to suffer the culminating vigour of Hannibal to sink and expire of itself, like a flame that flares up from scant and slight material.
