5.—The Book Revealed details

3. Sund’ring, dark’ning, thund’ring!
Rent away with a terrible crash
Eternity roll’d wide apart
Wide asunder rolling
Mountainous all around
Departing; departing; departing:
Leaving ruinous fragments of life
Hanging frowning cliffs & all between
An ocean of voidness unfathomable.

4. The roaring fires ran o’er the heav’ns
In whirlwinds & cataracts of blood
And o’er the dark desarts of Urizen
Fires pour thro’ the void on all sides
On Urizens self-begotten armies.

5. But no light from the fires. all was darkness
In the flames of Eternal fury

6. In fierce anguish & quenchless flames
To the desarts and rocks He ran raging
To hide, but He could not: combining
He dug mountains & hills in vast strength,
He piled them in incessant labour,
In howlings & pangs & fierce madness
Long periods in burning fires labouring
Till hoary, and age-broke, and aged,
In despair and the shadows of death.

7. And a roof, vast petrific around,
On all sides He fram’d: like a womb;
Where thousands of rivers in veins
Of blood pour down the mountains to cool
The eternal fires beating without
From Eternals; & like a black globe
View’d by sons of Eternity, standing
On the shore of the infinite ocean
Like a human heart strugling & beating
The vast world of Urizen appear’d.

8. And Los round the dark globe of Urizen,
Kept watch for Eternals to confine,
The obscure separation alone;
For Eternity stood wide apart.
