Lower Hell, inside the walls of Dis, in an illustration by Stradanus. There is a drop from the sixth circle to the three rings of the seventh circle, then again to the ten rings of the eighth circle, and, at the bottom, to the icy ninth circle.
Moated by the river Styx, the fortified city encloses the whole of Lower or Nether Hell.[2]
