89 YEARS BEFORE NIETZSCHE DECLARED THAT ‘GOD IS DEAD’ (1884), WILLIAM BLAKE HAD ONE OF HIS CHARACTERS – FUZON – DECLARE:

“Shall we worship this Demon of Smoke,”
Said Fuzon, “This abstract non-entity
This cloudy God seated on Waters
Now seen, now obscur’d; King of sorrow?”

Book of Ahania 1795

Fuzon rebelled against his tyrant father but then declared himself God - " the eldest of things!" And what  did God do? He crucified his own son for daring to question and judge his father! So, God killed God! He even crucified him! Ring any bells!

"Sudden sings the rock; swift & invisible
On Fuzon flew; enter’d his bosom.
His beautiful visage, his tresses
That gave light to the mornings of heaven
Were smitten with darkenss, deform’d
And outstretch’d on the edge of the forest …
 
With difficulty & great pain Urizen
Lifted on high the dead corse;
On his shoulders he bore it to where
A Tree hung over the Immensity …
 
The corse of his first begotten
on the accursed Tree of Mystery
On the topmost stem of this Tree."
Urizen nail’d Fuzon’s corse.
