bog (n.)
bog (v.)
O'er bog or steep, through strait, rough, dense, or rare,
With head, hands, wings, or feet, pursues his way,
And swims or sinks, or wades, or creeps, or flies.
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.
