AVERNUS, n.
The lake by which the ancients entered the infernal regions. The fact that access to the infernal regions was obtained by a lake is believed by the learned Marcus Ansello Scrutator to have suggested the Christian rite of baptism by immersion. This, however, has been shown by Lactantius to be an error.
_Facilis descensus Averni,_ The poet remarks; and the sense Of it is that when down-hill I turn I Will get more of punches than pence.
