The trump of Tartarus, with iron roar,
Called to the dwellers the black regions under:
Hell through its caverns trembled to the core,
And the blind air           to the thunder:
Never yet fiery bolt more fiercely tore
The crashing firmament, like rocks, asunder;
Nor with so huge a shudder earth's foundations
Shook to their mighty heart, lifting the nations.
