A gulf profound as that Serbonian bog
Betwixt Damiata and Mount Casius old,
Where armies whole have sunk: the parching air
Burns frore, and cold performs th’ effect of fire.
Thither by harpy-footed Furies hal’d,
At certain revolutions all the damn’d
Are brought, and feel by turns the bitter change
Of fierce extremes,—extremes by change more fierce;
From beds of raging fire to starve in ice
Their soft ethereal warmth, and there to pine
Immovable, infix’d, and frozen round,
Periods of time; thence hurried back to fire.

John Milton(1608–1674)
Paradise Lost. Book ii. Line 592.
