In the first book: To these Satan directs his speech, comforts them with hopes yet of regaining Heaven, but tells them lastly of a new world and new kind of creature to be created, according to an ancient prophecy or report in Heaven; for that Angels were long before this visible creation, was the opinion of many ancient Fathers. To find out the truth of this prophecy, and what to determine on, he refers to a full council. What his associates thence attempt. Pandemonium the palace of Satan rises, suddenly built out of the Deep; the infernal Peers there sit in council.



The consultation begun, Satan debates whether another battle be to be hazarded for the recovery of Heaven; some advise it, others dissuade: a third proposal is preferred, mentioned before by Satan, to search the truth of that prophecy or tradition in Heaven concerning another world, and another kind of creature, equal or not much inferior to themselves, about this time to be created; their doubt who shall be sent on this difficult search; Satan their chief undertakes alone the voyage, is honoured and applauded. The council thus ended, the rest betake them several ways, and to several employments, as their inclinations lead them, to entertain the time till Satan return.

Through many a dark and dreary vale
They passed, and many a region dolorous,
O’er many a frozen, many a fiery Alp,
Rocks, caves, lakes, fens, bogs, dens, and shades of death;
A universe of death, which God by curse
Created evil, for evil only good,
Where all life dies, death lives, and Nature breeds,
Perverse, all monstrous, all prodigious things,
Abominable, inutterable, and worse
Than fables yet have feigned or fear conceived,
Gorgons, and Hydras, and Chimæras dire.
He passes on his journey to Hell-gates, finds them shut, and who sat there to guard them,

Before the gates there sat
On either side a formidable shape;
The one seemed woman to the waist, and fair,
But ended foul in many a scaly fold,
Voluminous and vast, a serpent armed
With mortal sting. About her middle round
A cry of hell hounds never ceasing barked
With wide Cerberean mouths full loud, and rung
A hideous peal; yet, when they list, would creep,
If aught disturbed their noise, into her womb,
And kennel there, yet there still barked and howled
Within unseen.
The other shape —
If shape it might be called that shape had none
Distinguishable in member, joint or limb,
Or substance might be called that shadow seemed,
For each seemed either — black it stood as Night,
Fierce as ten Furies, terrible as Hell,
And shook a dreadful dart; what seemed his head
The likeness of a kingly crown had on.
Satan was now at hand, and from his seat
The monster moving onward came as fast
With horrid strides; Hell trembled as he strode.



… by whom at length they are opened, and discover to him the great gulf between Hell and Heaven; with what difficulty he passes through, directed by Chaos, the power of that place, to the sight of this new World which he sought.
That fury stayed —
Quenched in a boggy Syrtis, neither sea
Nor good dry land — nigh foundered on he fares,
Treading the crude consistence, half on foot,
Half flying; behoves him now both oar and sail.
As when a gryphon, through the wilderness
With winged course, o’r hill or moory dale,
Pursues the Arimaspian, who by stealth
Had from his wakeful custody purloined
The guarded gold: so eagerly the Fiend
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.

Or in the emptier waste, resembling air,
Weighs his spread wings, at leisure to behold
Far off the empyreal Heaven, extended wide
In circuit, undetermined square or round,
With opal towers and battlements adorned
Of living sapphire, once his native seat;
And fast by, hanging in a golden chain,
This pendent World, in bigness as a star
Of smallest magnitude close by the moon.
Thither, full fraught with mischievous revenge,
Accursed, and in a cursed hour, he hies.
