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
Immoveable, infix'd, and frozen round
Periods of time; thence hurried back to fire.
-- John Milton
