B~t in the time of that historian, as well as of Thucydides, the names of Oenotria and Italia, which appear to have been at that period regarded as synonymous, had been extended to include the shore of the Tarentine Gulf as far as Metapontum and from thence across to the gulfs of Laus and Posidonia on the Tyrrhenian Sea.
The boundaries of the original third Augustan region had by that time become somewhat altered, Metapontum belonging to Calabria, and Salernum and the territory of the Picentini to the third region instead of the first (Campania).
As a consequence of its having accepted Roman citizenship, it became a municipium; part of a copy of the Lex Iulia Municipalis of 46 B.C. (engraved on the back of two bronze tablets, on the front of which is a Greek inscription of the 3rd century B.C. defining the boundaries of lands belonging to various temples), which was found between Heraclea and Metapontum, is of the highest importance for our knowledge of that law.
After the Achaean cities had combined to destroy the Ionic Siris, and had founded Metapontum as a counterpoise to the Dorian Tarentum, there seems to have been little strife among the Italiotes.
At Corinth the unit was evidently the Assyrian and not the Attic, being 129.6 at the earliest (17) (though modified to double Attic, or 133, later) and being divided by 3, and not into 2 drachms. And this agrees with the mina being repeatedly found at Corcyra, and with the same standard passing to the Italian coinage (17) similar in weight, and in division into 1/3 -- the heaviest coinages (17) down to 400 B.C. (Terina, Velia, Sybaris, Posidonia, Metapontum, Tarentum, &c.) being none over 126, while later on many were adjusted to the Attic, and rose to 134.
