The Lake of Albano is the crater of an extinct volcano, near six miles in circumference. Castel-Gondolfo (a village built in the middle ages) stands on the top of the hill. The depth of this lake near Palazzola, the site of Alba Longa, is computed to be four hundred and eighty feet; and its subterranean canal, or outlet, called the Emissario, is one of the most extraordinary works of the ancient Romans, and was made during the seige of Veii, in obedience to the Delphic oracle. It is carried about a mile under the hill of Albano, to the plain. [P. 5.]
