BLAKE'S JERUSALEM

To understand Blake's figure of Jerusalem it is helpful to consider the personification of wisdom in other traditions.

Detail of Ulysses & Athena

The goddess Athena envisioned wisdom in the mythology of ancient Greece. She became the patron goddess of Athens, the city which exercised a powerful influence on the development of western civilization. Her birth took place from the head (or brain) of Zeus from whom all creation originated.  Athena played multiple roles in the Greek world. She assisted Gods and men by providing implements for them to accomplish their tasks. She provided counsel and protection to those under her guidance. Ulysses relied on her as he returned to Ithaca following the Trojan war. Her wisdom was not rational or intellectual thought, but relational and intuitive insight. 

William Blake's Circle of Destiny, by Milton O Percival gives this insight into Jerusalem:
 
"A sharer in Albion's fortunes is Jerusalem, the feminine half of the mystical union of contraries which is Albion. Upon her rests the ineffable grace and glory that distinguish others of her line - the kabbalistic Shekinah, the Gnostic Sophia, Dante's Blessed Virgin, the Celestial Virgin of Boehme. She is like Albion, an inclusive figure, the personification of his spiritual well-being, the result of the harmonious functioning of all his powers. She is designated as the sum of Albion's Emanations, the mother of his little ones, the aggregate of the Daughters of Inspiration, a tent and tabernacle of mutual forgiveness. She exists because in Eternity error is forgiven, nothing condemned. Among the children of Albion her name is 'Liberty' - the liberty of regenerated souls." (Page 17)

Milton, Plate 4, (E 98)
"If you account it Wisdom when you are angry to be silent, and
Not to shew it: I do not account that Wisdom but Folly.
Every Mans Wisdom is peculiar to his own Individuality"

Milton, Plate 25 [27],(E 122)
"And Los stood & cried to the Labourers of the Vintage in voice of awe.

Fellow Labourers! The Great Vintage & Harvest is now upon Earth
The whole extent of the Globe is explored: Every scatterd Atom
Of Human Intellect now is flocking to the sound of the Trumpet
All the Wisdom which was hidden in caves & dens, from ancient    
Time; is now sought out from Animal & Vegetable & Mineral

The Awakener is come. outstretchd over Europe! the Vision of God is fulfilled
The Ancient Man upon the Rock of Albion Awakes"

Milton,Plate 34 [38], (E 134)
"And Ololon looked down into the Heavens of Ulro in fear
They said. How are the Wars of Man which in Great Eternity 
Appear around, in the External Spheres of Visionary Life
Here renderd Deadly within the Life & Interior Vision
How are the Beasts & Birds & Fishes, & Plants & Minerals
Here fixd into a frozen bulk subject to decay & death?
Those Visions of Human Life & Shadows of Wisdom & Knowledge      
Plate 35 [39]
Are here frozen to unexpansive deadly destroying terrors.
And War & Hunting: the Two Fountains of the River of Life
Are become Fountains of bitter Death & of corroding Hell"

Four Zoas, Night II, Page 35, (E 325)
"What is the price of Experience do men buy it for a song
Or wisdom for a dance in the street? No it is bought with the price
Of all that a man hath his house his wife his children
Wisdom is sold in the desolate market where none come to buy
And in the witherd field where the farmer plows for bread in vain

It is an easy thing to triumph in the summers sun
And in the vintage & to sing on the waggon loaded with corn
It is an easy thing to talk of patience to the afflicted
To speak the laws of prudence to the houseless wanderer
...
It is an easy thing to rejoice in the tents of prosperity
Thus could I sing & thus rejoice, but it is not so with me!"

Four Zoas, Night III, Page 39, (E 326) 

[Advice to Urizen] 

"Leave all futurity to him Resume thy fields of Light 
Why didst thou listen to the voice of Luvah that dread morn
To give the immortal steeds of light to his deceitful hands
No longer now obedient to thy will thou art compell'd
To forge the curbs of iron & brass to build the iron mangers
To feed them with intoxication from the wine presses of Luvah

Till the Divine Vision & Fruition is quite obliterated
They call thy lions to the fields of blood, they rowze thy tygers
Out of the halls of justice, till these dens thy wisdom framd
Golden & beautiful but O how unlike those sweet fields of bliss  
Where liberty was justice & eternal science was mercy"

Four Zoas, Night VII, PAGE 80,(E 355)
"And Urizen Read in his book of brass in sounding tones 

Listen O Daughters to my voice Listen to the Words of Wisdom
So shall [ye] govern over all let Moral Duty tune your tongue 
But be your hearts harder than the nether millstone
To bring the shadow of Enitharmon beneath our wondrous tree   
That Los may Evaporate like smoke & be no more
Draw down Enitharmon to the Spectre of Urthona
And let him have dominion over Los the terrible shade
...
Reduce all to our will as spaniels are taught with art"

Vision of Last Judgment, (E 560)
 "General
Knowledge is Remote Knowledge it is in Particulars that Wisdom
consists & Happiness too.  Both in Art & in Life General Masses
are as Much Art as a Pasteboard Man is Human Every Man has Eyes
Nose & Mouth this Every Idiot knows but he who enters into &
discriminates most minutely the Manners & Intentions the
Characters in all their branches is the
alone Wise or Sensible Man & on this discrimination All Art is
founded.  I intreat then that the Spectator will attend to the
Hands & Feet to the Lineaments of the Countenances they are all
descriptive of Character & not a line is drawn without intention
& that most discriminate & particular" 

Annotations to Swedenborg, (E 603)
"He who Loves feels love descend into him & if he has wisdom
may percieve it is from the Poetic Genius which is the Lord"

Annotations to Swedenborg, (E 603)
   "Thought without affection makes a distinction between Love
& Wisdom as it does between body & Spirit"

In the New Testament we can see that wisdom was apparent in the one mind which we share with Christ and one another.

Phillipians 2
[1] So if there is any encouragement in Christ, any incentive of love, any participation in the Spirit, any affection and sympathy,
[2] complete my joy by being of the same mind, having the same love, being in full accord and of one mind.
[3] Do nothing from selfishness or conceit, but in humility count others better than yourselves.
[4] Let each of you look not only to his own interests, but also to the interests of others.
[5] Have this mind among yourselves, which is yours in Christ Jesus,
[6] who, though he was in the form of God, did not count equality with God a thing to be grasped,
[7] but emptied himself, taking the form of a servant, being born in the likeness of men.

In the Old Testament wisdom which was with God from the beginning, was a source of delight among men.

Proverbs 8
[1] Doth not wisdom cry? and understanding put forth her voice?
...
[22] The LORD possessed me in the beginning of his way, before his works of old.
[23] I was set up from everlasting, from the beginning, or ever the earth was.
[24] When there were no depths, I was brought forth; when there were no fountains abounding with water.
[25] Before the mountains were settled, before the hills was I brought forth:
[26] While as yet he had not made the earth, nor the fields, nor the highest part of the dust of the world.
[27] When he prepared the heavens, I was there: when he set a compass upon the face of the depth:
[28] When he established the clouds above: when he strengthened the fountains of the deep:
[29] When he gave to the sea his decree, that the waters should not pass his commandment: when he appointed the foundations of the earth:
[30] Then I was by him, as one brought up with him: and I was daily his delight, rejoicing always before him;
[31] Rejoicing in the habitable part of his earth; and my delights were with the sons of men.
[32] Now therefore hearken unto me, O ye children: for blessed are they that keep my ways.
[33] Hear instruction, and be wise, and refuse it not.
