1. Lo, a Shadow of horror is risen
In Eternity! unknown, unprolific,
Self-clos'd, all-repelling. What Demon
Hath form'd this abominable Void,
This soul-shudd'ring Vacuum? Some said
It is Urizen. But unknown, abstracted,
Brooding, secret, the dark Power hid.

2. Times on times he divided, and measur'd
Space by space in his ninefold darkness,
Unseen, unknown; changes appear'd
Like desolate mountains, rifted furious
By the black winds of perturbation.

3. For he strove in battles dire,
In unseen conflictions with Shapes,
Bred from his forsaken wilderness,
Of beast, bird, fish, serpent, and element,
Combustion, blast, vapour, and cloud.


4. Dark, revolving in silent activity,
Unseen in tormenting passions,
An Activity unknown and horrible,
A self-contemplating Shadow,
In enormous labours occupièd.
5. But Eternals beheld his vast forests;
Ages on ages he lay, clos'd, unknown,
Brooding, shut in the deep; all avoid
The petrific, abominable Chaos.

6. His cold horrors, silent, dark Urizen
Prepar'd; his ten thousands of thunders,
Rang'd in gloom'd array, stretch out across
The dread world; and the rolling of wheels,
As of swelling seas, sound in his clouds,

In his hills of stor'd snows, in his mountains
Of hail and ice; voices of terror
Are heard, like thunders of autumn,
When the cloud blazes over the harvests.
