prosecute their commerce with armed vessels and thus,
as occasion offered, to practise the trade of piracy also, and the
"Tyrrhene corsair" Postumius, whom Timoleon captured about 415, may
certainly have been an Antiate; but the Antiates were scarcely to be
reckoned among the naval powers of that period, and, had they been so,
the fact must from the attitude of Antium towards Rome have been
anything but an advantage to the latter. The extent to which the
Roman naval power had declined about the year 400 is shown by the
plundering of the Latin coasts by a Greek, presumably a Sicilian, war
fleet in 405, while at the same time Celtic hordes were traversing and
devastating the Latin land.(7) In the following year (406), and
beyond doubt under the immediate impression produced by these serious
events, the Roman community and the Phoenicians of Carthage, acting
respectively for themselves and for their dependent allies, concluded
a treaty of commerce and navigation-- the oldest Roman document of
which the text has reached us, although only in a Greek
translation.(8) In that treaty the Romans had to come under
obligation not to navigate the Libyan coast to the west of the Fair
Promontory (Cape Bon) excepting in cases of necessity. On the other
hand they obtained the privilege of freely trading, like the natives,
in Sicily, so far as it was Carthaginian; and in Africa and Sardinia
they obtained at least the right to dispose of their merchandise at a
price fixed with the concurrence of the Carthaginian officials and
guaranteed by the Carthaginian community. The privilege of free
trading seems to have been granted to the Carthaginians at least in
Rome, perhaps in all Latium; only they bound themselves neither to do
violence to the subject Latin communities,(9) nor, if they should set
foot as enemies on Latin soil, to take up their quarters for a night
on shore--in other words, not to extend their piratical inroads into
the interior--nor to construct any fortresses in the Latin land.

We may probably assign to the same period the already mentioned(10)
treaty between Rome and Tarentum, respecting the date of which we are
only told that it was concluded a considerable time before 472. By it
the Romans bound themselves--for what concessions on the part of
Tarentum is not stated--not to navigate the waters to the east of
the Lacinian promontory; a stipulation by which they were thus wholly
excluded from the eastern basin of the
