ACHERUSIA PALUS, a lake between Cumæ and the promontory Misenum, now Il Lago della Collucia. (Cluverius.) Some confound it with the Lacus Lucrinus, and others with the Lacus Avernus; but Strabo and Pliny distinguish them.—Also a lake of Epirus, through which the Acheron runs.—There is also a cave of the same name, through which Hercules is fabled to have descended to hell to drag forth Cerberus.—A small lake, near Hermione, in Argolis, bore the same name; and mention is made of another Acherusian lake near Memphis in Egypt.
