A spirit vaulting from a cloud to turn and wind a fiery Pegasus
you need to understand the legend of bellerophon to understand the picture
hint: it's from the male viewpoint
blake's gloss :
the horse of intellect is leaping from the cliffs of memory: it is a barren rock: it is also called the barren waste of locke and newton
curiously dali-esque that gloss, who copied who we can guess : o )
but imo you just want to look at the picture like a cartoon, it has quite a wry meaning : o ) !
Glittering in golden coats, like images;
As full of spirit as the month of May,
And gorgeous as the sun at midsummer;
Wanton as youthful goats, wild as young bulls.
I saw young Harry, with his beaver on,
His cuisses on his thighs, gallantly arm'd
Rise from the ground like feather'd Mercury,
And vaulted with such ease into his seat,
As if an angel dropp'd down from the clouds,
To turn and wind a fiery Pegasus
And witch the world with noble horsemanship
Like nets & gins & traps to catch the joys of Eternity
And all the rest a desart;
Till like a dream Eternity was obliterated & erased.
Since that dread day when Har and Heva fled.
Because their brethren & sisters liv'd in War & Lust;
And as they fled they shrunk
Into two narrow doleful forms:
Creeping in reptile flesh upon
The bosom of the ground:
And all the vast of Nature shrunk
Before their shrunken eyes.
Thus the terrible race of Los & Enitharmon gave
Laws & Religions to the sons of Har binding them more
And more to Earth: closing and restraining:
Till a Philosophy of Five Senses was complete
Urizen wept & gave it into the hands of Newton & Locke
Clouds roll heavy upon the Alps round Rousseau & Voltaire:
And on the mountains of Lebanon round the deceased Gods
Of Asia; & on the deserts of Africa round the Fallen Angels
The Guardian Prince of Albion burns in his nightly tent
