Avernus

Avernus is a deep lake in Italy, near Naples, 1½ m. in circumference, occupying the crater of an extinct volcano, at one time surrounded by a dark wood, and conceived, from its gloomy appearance, as well as from the mephitic vapours it exhaled, to be the entrance to the infernal world, and identified with it.
