f Tarentum: the six days' war with Falerii (513)
was little more than an interlude. But towards the north, between the
territory of the confederacy and the natural boundary of Italy--the
chain of the Alps--there still extended a wide region which was not
subject to the Romans. What was regarded as the boundary of Italy on
the Adriatic coast was the river Aesis immediately above Ancona.
Beyond this boundary the adjacent properly Gallic territory as far as,
and including, Ravenna belonged in a similar way as did Italy proper
to the Roman alliance; the Senones, who had formerly settled there,
were extirpated in the war of 471-2,(12) and the several townships
were connected with Rome, either as burgess-colonies, like Sena
Gallica,(13) or as allied towns, whether with Latin rights, like
Ariminum,(14) or with Italian rights, like Ravenna. On the wide
region beyond Ravenna as far as the Alps non-Italian peoples were
settled. South of the Po the strong Celtic tribe of the Boii still
held its ground (from Parma to Bologna); alongside of them, the
Lingones on the east and the Anares on the west (in the region of
Parma)--two smaller Celtic cantons presumably clients of the Boii--
peopled the plain. At the western end of the plain the Ligurians
began, who, mingled with isolated Celtic tribes, and settled on the
Apennines from above Arezzo and Pisa westward, occupied the region of
the sources of the Po. The eastern portion of the plain north of the
Po, nearly from Verona to the coast, was possessed by the Veneti, a
race different from the Celts and probably of Illyrian extraction.
Between these and the western mountains were settled the Cenomani
(about Brescia and Cremona) who rarely acted with the Celtic nation
and were probably largely intermingled with Veneti, and the Insubres
(around Milan). The latter was the most considerable of the Celtic
cantons in Italy, and was in constant communication not merely
with the minor communities partly of Celtic, partly of non-Celtic
extraction, that were scattered in the Alpine valleys, but also with
the Celtic cantons beyond the Alps. The gates of the Alps, the mighty
stream navigable for 230 miles, and the largest and most fertile plain
of the then civilized Europe, still continued in the hands of the
hereditary foes of the Italian name, who, humbled indeed and weakened,
but still scarce even nominally dependent and still troublesome
neighbours, persevered in their barbarism, and, thi
