Nor was war Rome’s only weapon against her enemies. Besides the ability of her generals and the discipline of her legions, she had the sagacity of her Senate. The Gauls were not wanting in intelligence or dexterity, but being too free to go quietly under a master’s hand, and too barbarous for self-government, carried away, as they were, by the interest or passion of the moment, they could not long act either in concert or with sameness of purpose. Far-sightedness and the spirit of persistence were, on the contrary, the familiar virtues of the Roman Senate. So soon as they had penetrated Cisalpine Gaul, they labored to gain there a permanent footing, either by sowing dissension amongst the Gallic peoplets that lived there, or by founding Roman colonies. In the year 283 B.C., several Roman families arrived, with colors flying and under the guidance of three triumvirs or commissioners, on a territory to the north-east, on the borders of the Adriatic. The triumvirs had a round hole dug, and there deposited some fruits and a handful of earth brought from Roman soil; then yoking to a plough, having a copper share, a white bull and a white heifer, they marked out by a furrow a large enclosure. The rest followed, flinging within the line the ridges thrown up by the plough. When the line was finished, the bull and the heifer were sacrificed with due pomp. It was a Roman colony come to settle at Sena, on the very site of the chief town of those Senonic Gauls who had been conquered and driven out. Fifteen years afterwards another Roman colony was founded at Ariminum (Rimini), on the frontier of the Bolan Gauls. Fifty years later still two others, on the two banks of the Po, Cremona and Placentia (Plaisance). Rome had then, in the midst of her enemies, garrisons, magazines of arms and provisions, and means of supervision and communication. Thence proceeded at one time troops, at another intrigues, to carry dismay or disunion amongst the Gauls.
