basins of the Rhone, the Rhine, and the Danube-- in the main lay beyond the political horizon of the Romans. We have now to set forth what steps were taken on the part of Rome to secure and to round off her empire in this direction, and how at the same time the great masses of peoples, who were ever moving to and fro behind that mighty mountain-screen, began to beat at the gates of the northern mountains and rudely to remind the Graeco-Roman world that it was mistaken in believing itself the sole possessor of the earth.
Let us first glance at the region between the western Alps and the Pyrenees. The Romans had for long commanded this part of the coast of the Mediterranean through their client city of Massilia, one of the oldest, most faithful, and most powerful of the allied communities dependent on Rome. Its maritime stations, Agatha (Agde) and Rhoda (Rosas) to the westward, and Tauroentium (Ciotat), Olbia (Hyeres?), Antipolis (Antibes), and Nicaea (Nice) on the east secured the navigation of the coast as well as the land-route from the Pyrenees to the Alps; and its mercantile and political connections reached far into the interior. An expedition into the Alps above Nice and Antibes, directed against the Ligurian Oxybii and Decietae, was undertaken by the Romans in 600 partly at the request of the Massiliots, partly in their own interest; and after hot conflicts, some of which were attended with much loss, this district of the mountains was compelled to furnish thenceforth standing hostages to the Massiliots and to pay them a yearly tribute. It is not improbable that about this same period the cultivation of the vine and olive, which flourished in this quarter after the model set by the Massiliots, was in the interest of the Italian landholders and merchants simultaneously prohibited throughout the territory beyond the Alps dependent on Massilia.(1) A similar character of financial speculation marks the war, which was waged by the Romans under
