From: The History of Rome, by Theodor Mommsen
Translated with the sanction of the author by William Purdie Dickson
That this station and any similar establishments which may have elsewhere existed on the coasts of Italy were neither of much importance nor of long standing, is evident from their having disappeared almost without leaving a trace. We have not the smallest reason to think them older than the Greek settlements of a similar kind on the same coasts.
An evidence of no slight weight that Latium at least first became acquainted with the men of Canaan through the medium of the Greeks is furnished by the Latin appellation "Poeni," which is borrowed from the Greek. All the oldest relations, indeed, of the Italians to the civilization of the east point decidedly towards Greece; and the rise of the Phoenician factory at Caere may be very well explained, without resorting to the pre-Greek period, by the subsequent well-known relations between the commercial state of Caere and Carthage.
In fact, when we recall the circumstance that the earliest navigation was and continued to be essentially of a coasting character, it is plain that scarcely any country on the Mediterranean lay so remote from the Phoenicians as the Italian mainland. They could only reach it either from the west coast of Greece or from Sicily; and it may well be believed that the seamanship of the Greeks became developed early enough to anticipate the Phoenicians in braving the dangers of the Adriatic and of the Tyrrhene seas.
There is no ground therefore for the assumption that any direct influence was originally exercised by the Phoenicians over the Italians. To the subsequent relations between the Phoenicians holding the supremacy of the western Mediterranean and the Italians inhabiting the shores of the Tyrrhene sea our narrative will return in the sequel.
