marshes did not exist, or were confined to a very limited space; but
from the decline of the Roman empire, the waters gradually encroached,

arrest their baleful progress. Before the drainage of Pope Sixtus, the
marshes covered at least thirteen thousand acres of ground, which in
the earlier ages was the most fruitful portion of the Italian soil.
