“Sylla threw this maritime part of Tuscany into enormous latifundia for his disbanded soldiers. Similar distributions continued to lessen its population during the Empire. In the younger Pliny’s time the climate was pestilential. The Lombards gave it a new aspect of misery. Wherever they found culture they built castles, and to each castle they allotted a ‘bandita’ or military fief. Hence baronial wars which have left so many picturesque ruins on the hills, and such desolation round them. Whenever a baron was conquered, his vassals escaped to the cities, and the vacant fief was annexed to the victorious. Thus stripped of men, the lands returned into a state of nature: some were flooded by the rivers, others grew into horrible forests, which enclose and concentrate the pestilence ofthe lakes and marshes.
