Since,
therefore, the disposition of the world is such by Nature, and all
other nations differ by their unbalanced temperament, it is in the true
mean within the space of all the world and the regions of the earth,
that the Roman people holds its territories. 11. For in
Italy the inhabitants are exactly tempered in either direction, both in
the structure of the body, and by their strength of mind in the matter
of endurance and courage. For just as the planet Jupiter is
tempered by running in the middle between the heat of Mars and the cold
of Saturn, in the same manner Italy presents good qualities which are
tempered by admixture from either side both north and south, and are
consequently unsurpassed. And so, by its policy, it curbs the
courage of the northern barbarians, by its strength, the imaginative
south. Thus the divine mind has allotted to the Roman state an
excellent and temperate region in order to rule the world.
(Vitruvius, On Architecture, Book VI, 17-19)
