Mundane 2

From Wikipedia:
Book II of 'Milton' finds Blake in the garden of his cottage in Felpham. 
Ololon, a female figure linked to Milton, descends to meet him. Blake 
sees a skylark, which mutates into a twelve-year-old girl, who he thinks 
is one of his own muses. He invites her into his cottage to meet his wife. 
The girl states that she is actually looking for Milton. Milton then descends 
to meet with her, and in an apocalyptic scene he is eventually unified with 
the girl, who is identified as Ololon and becomes his own feminine aspect.

Plate 33 of Book of Milton (Erdman 133-34)
But Ololon sought the Or-Ulro & its fiery Gates
And the Couches of the Martyrs: & many Daughters of Beulah
Accompany them down to the Ulro with soft melodious tears
A long journey & dark thro Chaos in the track of Miltons course
To where the Contraries of Beulah War beneath Negations Banner
Then view'd from Miltons Track they see the Ulro: a vast Polypus
Of living fibres down into the Sea of Time & Space growing
A self-devouring monstrous human Death Twenty-seven fold
Within it sit Five Females & the nameless Shadowy Mother
Spinning it from their bowels with songs of amorous delight
And melting cadences that lure the Sleepers of Beulah down
The River Storge (which is Arnon) into the Dead Sea:
Around this Polypus Los continual builds the Mundane Shell
Four Universes round the Universe of Los remain Chaotic
Four intersecting Globes, & the Egg form'd World of Los
In midst; stretching from Zenith to Nadir, in midst of Chaos.
One of these Ruind Universes is to the North named Urthona
One to the South this was the glorious World of Urizen
One to the East, of Luvah: One to the West; of Tharmas.
But when Luvah assumed the World of Urizen in the South
All fell towards the Center sinking downward in dire Ruin

PLATE 59 of Jerusalem:
And formed into Four precious stones. for enterance from Beulah
For the Veil of Vala which Albion cast into the Atlantic Deep
To catch the Souls of the Dead: began to Vegetate & Petrify
Around the Earth of Albion. among the Roots of his Tree
This Los formed into the Gates & mighty Wall, between the Oak
Of Weeping & the Palm of Suffering beneath Albions Tomb,
Thus in process of time it became the beautiful Mundane Shell,
The Habitation of the Spectres of the Dead & the Place
Of Redemption & of awaking again into Eternity
For Four Universes round the Mundane Egg remain Chaotic
One to the North; Urthona: One to the South; Urizen:
One to the East: Luvah: One to the West, Tharmas;
They are the Four Zoas that stood around the Throne Divine
Verulam: London: York & Edinburgh: their English names
But when Luvah assumed the World of Urizen Southward
(/Erdman 2O7-8)

From Jerusalem Plate 92 (Erdman 251-2):
Amalek, Edom, Egypt, Moab, Ammon, Ashur, Philistea, around Jerusalem
Where the Druids reard their Rocky Circles to make permanent Remembrance
Of Sin. & the Tree of Good & Evil sprang from the Rocky Circle & Snake
Of the Druid, along the Valley of Rephaim from Camberwell to Golgotha
And framed the Mundane Shell Cavernous in Length Bredth & Highth
