Note 1977 — Chapter IV
W. (William) Falconer translation
Strabo is not the only one who mentions this: Virgil says,
“Spelunca alta fuit, vastoque immanis hiatu, Scrupea, tuta lacu nigro, nemorumque tenebris; Quam super haud ullæ poterant impune volantes Tendere iter pennis; talis sese halitus atris Faucibus effundens supera ad convexa ferebat; Unde locum Graii dixerunt nomine Avernum.” Æneid. vi. 237.
