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.

Heaven is for thee too high To know what passes there; be lowly wise. Think only what concerns thee and thy being; Dream not of other worlds, what creatures there Live, in what state, condition, or degree, Contented that thus far hath been revealed.

The rising world of waters dark and deep.

Revenge, at first though sweet, Bitter ere long back on itself recoils.

Thou canst not touch the freedom of my mind.

Imparadis'd in one another's arms.

Heaven open'd wide Her ever during gates, harmonious sound, On golden hinges moving.
