With the more western Ligurian tribes, who held the Genoese Apennines
and the Maritime Alps, there were incessant conflicts. They were
troublesome neighbours, accustomed to pillage by land and by sea: the
Pisans and Massiliots suffered no little injury from their incursions
and their piracies.
But no permanent results were gained amidst these
constant hostilities, or perhaps even aimed at; except apparently
that, with a view to have a communication by land with Transalpine
Gaul and Spain in addition to the regular route by sea, the Romans
endeavoured to clear the great coast road from Luna by way of Massilia
to Emporiae, at least as far as the Alps--beyond the Alps it devolved
on the Massiliots to keep the coast navigation open for Roman vessels
and the road along the shore open for travellers by land.
interior with its impassable valleys and its rocky fastnesses,
and with its poor but dexterous and crafty inhabitants, served
the Romans mainly as a school of war for the training and hardening
of soldiers and officers.
