Avernus

"There, when at Cumae landing from the main, / Avernus' lakes and sounding woods ye gain, / thyself shalt see, within her rock-hewn shrine, / the frenzied prophetess, whose mystic strain / expounds the Fates, to leaves of trees consign / the notes and names that mark the oracles divine."

His fiery eies are fixt vpon the earth. As if he now deuiſ’d some Stratageme: Or meant to pierce Auernus darkſome vauts. To pull the triple headed dog from hell.

I perceive the Lake Avernus, an extinguished volcano, whose waves once inspired terror.
