Their leader, however, pursued a course different from that of his
predecessors. Quintus Fabius was a man advanced in years, of a
deliberation and firmness, which to not a few seemed procrastination
and obstinacy. Zealous in his reverence for the good old times, for
the political omnipotence of the senate, and for the command of the
burgomasters, he looked to a methodical prosecution of the war as
--next to sacrifices and prayers--the means of saving the state.
A political antagonist of Gaius Flaminius, and summoned to the head of
affairs in virtue of the reaction against his foolish war-demagogism,
Fabius departed for the camp just as firmly resolved to avoid a
pitched battle at any price, as his predecessor had been determined at
any price to fight one; he was without doubt convinced that the first
elements of strategy would forbid Hannibal to advance so long as the
Roman army confronted him intact, and that accordingly it would not be
difficult to weaken by petty conflicts and gradually to starve out the
enemy's army, dependent as it was on foraging for its supplies.
