cannot say, therefore, whether this formation in three lines is in any
way traceable to experience dearly bought in wars with Italian
highlanders, or to a lesson taught by the terrible onset of the Gaul.
Again, the punctilious care in the entrenchment of the camp, even for a
night's halt, which moved the admiration of Pyrrhus and was a material
part of Roman tactics, was likely to be inculcated by the perils to
which a burgher army would be exposed in carrying on war under or among
hills where it would be always liable to the sudden attack of a swift,
sure-footed, and wily foe. The habit of carrying a heavy load of
palisades on the march would be a part of the same necessity.

Even from the purely military point of view, then, the She-wolf and the
Twins seem to us not appropriate emblems of Roman greatness. A better
frontispiece for historians of Rome, if we mistake not, would be some
symbol of the patroness of the lowlands and their protectress against
the wild tribes of the highlands. There should also be something to
symbolize the protectress of Italy against the Gauls, whose irruptions
Rome, though defeated at Allia, succeeded ultimately in arresting and
hurling back, to the general benefit of Italian civilization which, we
may be sure, felt very grateful to her for that service, and remembered
it when her existence was threatened by Hannibal, with Gauls in his
army. Capua, though not so well situated for the leadership of Italy,
might have played the part of Rome; but the plain which she commanded,
though very rich, was too small, and too closely overhung by the fatal
hills of the Samnite, under whose dominion she fell. Rome had space to
organize a strong lowland resistance to the marauding highland powers.
It seems probable that her hills were not only the citadel but the
general refuge of the lowlanders of those parts, when forced to fly
before the onslaught of the highlanders, who were impelled by successive
wars of migration to the plains. The Campagna affords no stronghold or
