vessel (360).  The Antiates indeed continued to 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 Mediterranean.

Roman Fortification of the Coast

These were disasters no less than the defeat on the Allia, and the Roman senate seems to have felt them as such and to have made use of the favourable turn, which the Italian relations assumed soon after the conclusion of the humiliating treaties with Carthage and Tarentum, with all energy to improve its depressed maritime position.  The most important of the coast towns were furnished with Roman colonies:
