Those sooty fiends which Nature keeps,

Bolted and barr'd up in the deeps;

50Black caves, wide chasms, which who see confess

Types of the pit, so deep, so bottomless!

These mysteries, though I fain would not behold,

You to my view unfold:

Like an old Roman criminal, to the high

Tarpeian Hill you force me up, that I

May so be hurried headlong down, and die.
