Four Zoas, Night VII, Page 80, (E 356) "Urizen envious brooding sat & saw the secret terror Flame high in pride & laugh to scorn the source of his deceit Nor knew the source of his own but thought himself the Sole author
PAGE 81 Of all his wandering Experiments in the horrible Abyss He knew that weakness stretches out in breadth & length he knew That wisdom reaches high & deep & therefore he made Orc In Serpent form compelld stretch out & up the mysterious tree He sufferd him to Climb that he might draw all human forms Into submission to his will nor knew the dread result Los sat in showers of Urizen watching cold Enitharmon His broodings rush down to his feet producing Eggs that hatching Burst forth upon the winds above the tree of Mystery Enitharmon lay on his knees. Urizen tracd his Verses In the dark deep the dark tree grew. her shadow was drawn down Down to the roots it wept over Orc. the Shadow of Enitharmon Los saw her stretchd the image of death upon his witherd valleys Her Shadow went forth & returnd Now she was pale as Snow When the mountains & hills are coverd over & the paths of Men shut up But when her spirit returnd as ruddy as a morning when The ripe fruit blushes into joy in heavens eternal halls Sorrow shot thro him from his feet it shot up to his head Like a cold night that nips the root & shatters off the leaves Silent he stood oer Enitharmon watching her pale face He spoke not he was Silent till he felt the cold disease Then Los mournd on the dismal wind in his jealous lamentation Why can I not Enjoy thy beauty Lovely Enitharmon When I return from clouds of Grief in the wandring Elements Where thou in thrilling joy in beaming summer loveliness Delectable reposest ruddy in my absence flaming with beauty Cold pale in sorrow at my approach trembling at my terrific Forehead & eyes thy lips decay like roses in the spring How art thou Shrunk thy grapes that burst in summers vast Excess Shut up in little purple covering faintly bud & die Thy olive trees that pourd down oil upon a thousand hills Sickly look forth & scarcely stretch their branches to the plain Thy roses that expanded in the face of glowing morn."
Blake uses an illustrations from his engravings for Young's Night Thoughts to accompany his text for page 81 of the Four Zoas. The connection of the image to his account of the Serpent being forced to climb the Tree of Mystery, and Los feeling estranged from Enitharmon is less than obvious. We must look deeper to see the figure in the picture as Urizen as he with one hand tears down the sun, with the other aims a spear of destruction. Underfoot Urizen tramples two figures who have opposed him.

Early in Blake's passage he calls to mind that it was Jesus who was raised on the tree, lifted up and drew all men to him.
 Jesus answered and said, This voice came not because of me, but for your sakes.
 Now is the judgment of this world: now shall the prince of this world be cast out.
 And I, if I be lifted up from the earth, will draw all men unto me.
