My mansion is, where those immortal shapes Of bright aerial spirits live insphered In regions mild of calm and serene air, Above the smoke and stir of this dim spot Which men call Earth.
John MiltonA 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
