Blake did not name his culminating epic after Albion, he named it after Jerusalem, Albion's Emanation, the active, spiritual aspect of the sleeping Albion in the poem Jerusalem. Albion cast Jerusalem from his bosom when he invited Vala in. To Albion Vala represented the exterior world (or the body) produced by time and space. He "fell in love with the productions of time." Jerusalem's fate was to leave the Eternal World and wander until body and soul, Vala and Jerusalem were reunited.
In this passage on Plate 85 Jerusalem is threefold, Head and Heart and Reins, "not yet embodied in Time and Space."
In the image on the title plate, the butterfly Jerusalem is caught in her cocoon waiting for release. Like Albion's, her Eternal form includes the stars, the moon in two phases, the sun, and the earth. Surrounding the sleeping Jerusalem are emanations which appear to be Vala (Heart) to the left, Ahania (Head) above, and Enion (Reins) to the right.
Jerusalem, Plate 85, (E 165)
"O lovely mild Jerusalem! O Shiloh of Mount Ephraim!
I see thy Gates of precious stones: thy Walls of gold & silver
Thou art the soft reflected Image of the Sleeping Man
Who stretchd on Albions rocks reposes amidst his Twenty-eight
Cities: where Beulah lovely terminates, in the hills & valleys of Albion
Cities not yet embodied in Time and Space: plant ye
The Seeds O Sisters in the bosom of Time & Spaces womb
To spring up for Jerusalem: lovely Shadow of Sleeping Albion
Why wilt thou rend thyself apart & build an Earthly Kingdom
To reign in pride & to opress & to mix the Cup of Delusion
O thou that dwellest with Babylon! Come forth O lovely-one
I see thy Form O lovely mild Jerusalem, Wingd with Six Wings
In the opacous Bosom of the Sleeper, lovely Three-fold
In Head & Heart & Reins, three Universes of love & beauty
Thy forehead bright: Holiness to the Lord, with Gates of pearl
Reflects Eternity beneath thy azure wings of feathery down
Ribbd delicate & clothd with featherd gold & azure & purple
From thy white shoulders shadowing, purity in holiness!
Thence featherd with soft crimson of the ruby bright as fire
Spreading into the azure Wings which like a canopy
Bends over thy immortal Head in which Eternity dwells
Albion beloved Land; I see thy mountains & thy hills
And valleys & thy pleasant Cities Holiness to the Lord
I see the Spectres of thy Dead O Emanation of Albion.
Thy Bosom white, translucent coverd with immortal gems
A sublime ornament not obscuring the outlines of beauty
Terrible to behold for thy extreme beauty & perfection
Twelve-fold here all the Tribes of Israel I behold
Upon the Holy Land: I see the River of Life & Tree of Life
I see the New Jerusalem descending out of Heaven
Between thy Wings of gold & silver featherd immortal
Clear as the rainbow, as the cloud of the Suns tabernacle
Thy Reins coverd with Wings translucent sometimes covering
And sometimes spread abroad reveal the flames of holiness
Which like a robe covers: & like a Veil of Seraphim
In flaming fire unceasing burns from Eternity to Eternity
Twelvefold I there behold Israel in her Tents
A Pillar of a Cloud by day: a Pillar of fire by night
Guides them: there I behold Moab & Ammon & Amalek
There Bells of silver round thy knees living articulate
Comforting sounds of love & harmony & on thy feet
Sandals of gold & pearl, & Egypt & Assyria before me
The Isles of Javan, Philistea, Tyre and Lebanon
Thus Los sings upon his Watch walking from Furnace to Furnace.
But when they saw Albion fall'n upon mild Lambeths vale:
Astonish'd! Terrified! they hover'd over his Giant limbs.
Then thus Jerusalem spoke, while Vala wove the veil of tears:
Weeping in pleadings of Love, in the web of despair.
Wherefore hast thou shut me into the winter of human life
And clos'd up the sweet regions of youth and virgin innocence:
Where we live, forgetting error, not pondering on evil:
Among my lambs & brooks of water, among my warbling birds:
Where we delight in innocence before the face of the Lamb:
Going in and out before him in his love and sweet affection.
Vala replied weeping & trembling, hiding in her veil.
When winter rends the hungry family and the snow falls:
Upon the ways of men hiding the paths of man and beast,
Then mourns the wanderer: then he repents his wanderings & eyes
The distant forest; then the slave groans in the dungeon of stone.
The captive in the mill of the stranger, sold for scanty hire.
They view their former life: they number moments over and over;
Stringing them on their remembrance as on a thread of sorrow.
Thou art my sister and my daughter! thy shame is mine also!
Ask me not of my griefs! thou knowest all my griefs.
Jerusalem answer'd with soft tears over the valleys.
O Vala what is Sin? that thou shudderest and weepest
At sight of thy once lov'd Jerusalem! What is Sin but a little
Error & fault that is soon forgiven; but mercy is not a Sin
Nor pity nor love nor kind forgiveness! O! if I have Sinned
Forgive & pity me! O! unfold thy Veil in mercy & love!
Slay not my little ones, beloved Virgin daughter of Babylon
Slay not my infant loves & graces, beautiful daughter of Moab
I cannot put off the human form I strive but strive in vain
When Albion rent thy beautiful net of gold and silver twine;
Thou hadst woven it with art, thou hadst caught me in the bands
Of love; thou refusedst to let me go: Albion beheld thy beauty
Beautiful thro' our Love's comeliness, beautiful thro' pity.
The Veil shone with thy brightness in the eyes of Albion,
Because it inclosd pity & love; because we lov'd one-another!
Albion lov'd thee! he rent thy Veil! he embrac'd thee! he lov'd thee!
Astonish'd at his beauty & perfection, thou forgavest his furious love:
I redounded from Albions bosom in my virgin loveliness.
The Lamb of God reciev'd me in his arms he smil'd upon us:
He made me his Bride & Wife: he gave thee to Albion.
Then was a time of love: O why is it passed away!"
