which subjected to the Carthaginians the Greek cities of Thermae (the
ancient Himera), Segesta, Heraclea Minoa, Selinus, and a part of the
territory of Agrigentum as far as the Halycus, was regarded by the two
powers contending for the possession of the island as only a temporary
accommodation; on both sides the rivals were ever renewing their
attempts to dispossess each other. Four several times--in 360 in the
time of Dionysius the elder; in 410 in that of Timoleon; in 445 in
that of Agathocles; in 476 in that of Pyrrhus--the Carthaginians were
masters of all Sicily excepting Syracuse, and were baffled by its
solid walls; almost as often the Syracusans, under able leaders, such
as were the elder Dionysius, Agathocles, and Pyrrhus, seemed equally
on the eve of dislodging the Africans from the island. But more and
more the balance inclined to the side of the Carthaginians, who were,
as a rule, the aggressors, and who, although they did not follow out
their object with Roman steadfastness, yet conducted their attack with
far greater method and energy than the Greek city, rent and worn out
by factions, conducted its defence. The Phoenicians might with reason
expect that a pestilence or a foreign -condottiere- would not always
snatch the prey from their hands; and for the time being, at least at
sea, the struggle was already decided:(5) the attempt of Pyrrhus to
re-establish the Syracusan fleet was the last. After the failure of
that attempt, the Carthaginian fleet commanded without a rival the
whole western Mediterranean; and their endeavours to occupy Syracuse,
Rhegium, and Tarentum, showed the extent of their power and the
objects at which they aimed. Hand in hand with these attempts went
the endeavour to monopolize more and more the maritime commerce of
this region, at the expense alike of foreigners and of their own
subjects; and it was not the wont of the Carthaginians to recoil from
any violence that might help forward their purpose. A contemporary
of the Punic wars, Eratosthenes, the father of geography (479-560),
