Then Urizen arose upon the wind back many a mile
Retiring into his dire Web scattering fleecy snows
As he ascended howling loud the Web vibrated strong
From heaven to heaven from globe to globe. In vast excentric paths
Compulsive rolld the Comets at his dread command the dreary way
Falling with wheel impetuous down among Urthonas vales
And round red Orc returning back to Urizen gorged with blood
Slow roll the massy Globes at his command & slow oerwheel
The dismal squadrons of Urthona. weaving the dire Web
In their progressions & preparing Urizens path before him
