Twilight upon the Earth, short Arbiter
Twixt Day and Night, and now from end to end
Nights Hemisphere had veild the Horizon round:
When SATAN who late fled before the threats
Of GABRIEL out of EDEN, now improv'd
In meditated fraud and malice, bent
On mans destruction, maugre what might hap
Of heavier on himself, fearless return'd.
By Night he fled, and at Midnight return'd
From compassing the Earth, cautious of day,
Since URIEL Regent of the Sun descri'd
His entrance, and forewarnd the Cherubim
That kept thir watch; thence full of anguish driv'n,
The space of seven continu'd Nights he rode
With darkness, thrice the Equinoctial Line
He circl'd, four times cross'd the Carr of Night
From Pole to Pole, traversing each Colure;
On the eighth return'd, and on the Coast averse
From entrance or Cherubic Watch, by stealth
Found unsuspected way. There was a place,
Now not, though Sin, not Time, first wraught the change,
Where TIGRIS at the foot of Paradise
Into a Gulf shot under ground, till part
Rose up a Fountain by the Tree of Life;
In with the River sunk, and with it rose
Satan involv'd in rising Mist, then sought
Where to lie hid; Sea he had searcht and Land
From EDEN over PONTUS, and the Poole
MAEOTIS, up beyond the River OB;
Downward as farr Antartic; and in length
