Albānus Lacus
A small lake, about five miles in circumference, west of the Mons Albanus, between Bovillae
and Alba Longa. It is the crater of an extinct volcano, and is many hundred feet deep. The
emissarium which the Romans bored through the solid rock during the
siege of Veii, in order to carry off the superfluous water of the lake, is extant at the
present day. See
Emissarium.
