Coeus, and Gyges, and Briareus,
Typhon, and Dolor, and Porphyrion, 20
With many more, the brawniest in assault,
Were pent in regions of laborious breath;
Dungeon'd in opaque element, to keep
Their clenched teeth still clench'd, and all their limbs
Lock'd up like veins of metal, crampt and screw'd;
Without a motion, save of their big hearts
Heaving in pain, and horribly convuls'd
With           feverous boiling gurge of pulse.
