Italy, taken as a whole, is a triangle, of which the eastern side is bounded by the Ionian Sea and the Adriatic Gulf, its southern and western sides by the Sicilian and Tyrrhenian seas; these two sides converge to form the apex of the triangle, which is represented by the southern promontory of Italy called Cocinthus, and which separates the Ionian from the Sicilian Sea.[146] The third side, or base of this triangle, is on the north, and is formed by the chain of the Alps stretching right across the country, beginning at Marseilles and the coast of the Sardinian Sea, and with no break in its continuity until within a short distance of the head of the Adriatic. To the south of this range, which I said we must regard as the base of the triangle, are the most northerly plains of Italy, the largest and most fertile of any with which I am acquainted in all Europe. This is the district with which we are at present concerned. Taken as a whole, it too forms a triangle, the apex of which is the point where the Apennines and Alps converge, above Marseilles, and not far from the coast of the Sardinian Sea. The northern side of this triangle is formed by the Alps, extending for 2200 stades; the southern by the Apennines, extending 3600; and the base is the seaboard of the Adriatic, from the town of Sena to the head of the gulf, a distance of more than 2500 stades. The total length of the three sides will thus be nearly 10,000 stades.

The quantity of panic and millet produced is extraordinary; and the amount of acorns grown in the oak forests scattered about the country may be gathered from the fact that, though nowhere are more pigs slaughtered than in Italy, for sacrifices as well as for family use, and for feeding the army, by far the most important supply is from these plains. The cheapness and abundance of all articles of food may also be clearly shown from the fact that travellers in these parts, when stopping at inns, do not bargain for particular articles, but simply ask what the charge is per head for board. And for the most part the innkeepers are content to supply their guests with every necessary at a charge rarely exceeding half an as (that is, the fourth part of an obol)[147] a day each. Of the numbers, stature, and personal beauty of the inhabitants, and still more of their bravery in war, we shall be able to satisfy ourselves from the facts of their history.
