"My own ultraviolet darling. " Lolita - Vladimir Nabokov

...that swimming, sloping, elusive something about the dark-bluish tint of the iris which seemed still to retain the shadows it had absorbed of ancient, fabulous forests where there were more birds than tigers and more fruit than thorns, and where, in some dappled depth, man's mind had been born...

I was the shadow of the waxwing slain
By the false azure in the windowpane;
I was the smudge of ashen fluff -and I
Lived on, flew on, in the reflected sky.
And from the inside, too, I'd duplicate
Myself, my lamp, an apple on a plate:
Uncurtaining the night, I'd let dark glass
Hang all the furniture above the grass,
And how delightful when a fall of snow
Covered my glimpse of lawn and reached up so
As to make chair and bed exactly stand
Upon that snow, out in that crystal land!

The spiral is a spiritualized circle. In the spiral form, the circle, uncoiled, has ceased to be vicious; it has been set free.
