—­Nature breeds,
  Perverse, all monstrous, all prodigious Things,
  Abominable, inutterable, and worse
  Than Fables yet have feign’d, or Fear conceiv’d,
  Gorgons, and Hydras, and Chimeras dire.

This Episode of the fallen Spirits, and their Place of Habitation, comes in very happily to unbend the Mind of the Reader from its Attention to the Debate.  An ordinary Poet would indeed have spun out so many Circumstances to a great Length, and by that means have weakned, instead of illustrated, the principal Fable.

The Flight of Satan to the Gates of Hell is finely imaged.  I have already declared my Opinion of the Allegory concerning Sin and Death, which is however a very finished Piece in its kind, when it is not considered as a Part of an Epic Poem.  The Genealogy of the several Persons is contrived with great Delicacy.  Sin is the Daughter of Satan, and Death the Offspring of Sin.  The incestuous Mixture between Sin and Death produces those Monsters and Hell-hounds which from time to time enter into their Mother, and tear the Bowels of her who gave them Birth.  These are the Terrors of an evil Conscience, and the proper Fruits of Sin, which naturally rise from the Apprehensions of Death.  This last beautiful Moral is, I think, clearly intimated in the Speech of Sin, where complaining of this her dreadful Issue, she adds,

  Before mine Eyes in Opposition sits
  Grim Death my Son and Foe, who sets them on,
  And me his Parent would full soon devour
  For want of other Prey, but that he knows
  His End with mine involv’d—­

I need not mention to the Reader the beautiful Circumstance in the last Part of this Quotation.  He will likewise observe how naturally the three Persons concerned in this Allegory are tempted by one common Interest to enter into a Confederacy together, and how properly Sin is made the Portress of Hell, and the only Being that can open the Gates to that World of Tortures.

The descriptive Part of this Allegory is likewise very strong, and full of Sublime Ideas.  The Figure of Death, [the Regal Crown upon his Head,] his Menace of Satan, his advancing to the Combat, the Outcry at his Birth, are Circumstances too noble to be past over in Silence, and extreamly suitable to this King of Terrors.  I need not mention the Justness of Thought which is observed in the Generation of these several Symbolical Persons; that Sin was produced upon the first Revolt of Satan, that Death appear’d soon after he was cast into Hell, and that the Terrors of Conscience were conceived at the Gate of this Place of Torments.  The Description of the Gates is very poetical, as the opening of them is full of Milton’s Spirit.

 —­On a sudden open fly
  With impetuous Recoil and jarring Sound
  Th’ infernal Doors, and on their Hinges grate
  Harsh Thunder, that the lowest Bottom shook
  Of Erebus.  She open’d, but to shut
  Excell’d her Powr; the Gates wide
