Now the thought Both of lost happiness and lasting pain Torments him; round he throws his baleful eyes That witnessed huge affliction and dismay Mixed with obdurate pride and steadfast hate: At once as far as angels ken he views The dismal situation waste and wild, A dungeon horrible, on all sides round As one great furnace flamed, yet from those flames No light, but rather darkness visible Served only to discover sights of woe, Regions of sorrow, doleful shades, where peace And rest can never dwell, hope never comes That comes to all; but torture without end Still urges, and a fiery deluge, fed With ever-burning sulfur unconsumed.
