And men, to sound depths, so much line untie,
As one might justly thinke, that there would rise
At end thereof, one of th'Antipodies:
If under all, a Vault infernall bee, 295
(Which sure is spacious, except that we
Invent another torment, that there must
          into a straight hot roome be thrust)
Then solidnesse, and roundnesse have no place.
