On the stiff twig up there
Hunches a wet black rook
Arranging and rearranging its feathers in the rain.
I do not expect a miracle
Or an accident

To set the sight on fire
In my eye, not seek
Any more in the desultory weather some design,
But let spotted leaves fall as they fall,
Without ceremony, or portent.

Although, I admit, I desire,
Occasionally, some backtalk
From the mute sky, I can't honestly complain:
A certain minor light may still
Leap incandescent

Out of the kitchen table or chair
As if a celestial burning took
Possession of the most obtuse objects now and then ---
Thus hallowing an interval
Otherwise inconsequent

By bestowing largesse, honor,
One might say love. At any rate, I now walk
Wary (for it could happen
Even in this dull, ruinous landscape); sceptical,
Yet politic; ignorant

Of whatever angel may choose to flare
Suddenly at my elbow. I only know that a rook
Ordering its black feathers can so shine
As to seize my senses, haul
My eyelids up, and grant

A brief respite from fear
Of total neutrality. With luck,
Trekking stubborn through this season
Of fatigue, I shall
Patch together a content

Of sorts. Miracles occur,
If you care to call those spasmodic
Tricks of radiance miracles. The wait's begun again,
The long wait for the angel.
For that rare, random descent.

Love set you going like a fat gold watch.
The midwife slapped your footsoles, and your bald cry
Took its place among the elements.

Our voices echo, magnifying your arrival. New statue.
In a drafty museum, your nakedness
Shadows our safety. We stand round blankly as walls.

I’m no more your mother
Than the cloud that distills a mirror to reflect its own slow
Effacement at the wind’s hand.

All night your moth-breath
Flickers among the flat pink roses. I wake to listen:
A far sea moves in my ear.

One cry, and I stumble from bed, cow-heavy and floral
In my Victorian nightgown.
Your mouth opens clean as a cat’s. The window square

Whitens and swallows its dull stars. And now you try
Your handful of notes;
The clear vowels rise like balloons.

I am silver and exact. I have no preconceptions.
Whatever I see I swallow immediately
Just as it is, unmisted by love or dislike.
I am not cruel, only truthful ‚
The eye of a little god, four-cornered.
Most of the time I meditate on the opposite wall.
It is pink, with speckles. I have looked at it so long
I think it is part of my heart. But it flickers.
Faces and darkness separate us over and over.

Now I am a lake. A woman bends over me,
Searching my reaches for what she really is.
Then she turns to those liars, the candles or the moon.
I see her back, and reflect it faithfully.
She rewards me with tears and an agitation of hands.
I am important to her. She comes and goes.
Each morning it is her face that replaces the darkness.
In me she has drowned a young girl, and in me an old woman
Rises toward her day after day, like a terrible fish.

I know the bottom, she says. I know it with my great tap root:
It is what you fear.
I do not fear it: I have been there.

Is it the sea you hear in me,
Its dissatisfactions?
Or the voice of nothing, that was your madness?

Love is a shadow.
How you lie and cry after it
Listen: these are its hooves: it has gone off, like a horse.

All night I shall gallop thus, impetuously,
Till your head is a stone, your pillow a little turf,
Echoing, echoing.

Or shall I bring you the sound of poisons?
This is rain now, this big hush.
And this is the fruit of it: tin-white, like arsenic.

I have suffered the atrocity of sunsets.
Scorched to the root
My red filaments burn and stand, a hand of wires.

Now I break up in pieces that fly about like clubs.
A wind of such violence
Will tolerate no bystanding: I must shriek.

The moon, also, is merciless: she would drag me
Cruelly, being barren.
Her radiance scathes me. Or perhaps I have caught her.

I let her go. I let her go
Diminished and flat, as after radical surgery.
How your bad dreams possess and endow me.

I am inhabited by a cry.
Nightly it flaps out
Looking, with its hooks, for something to love.

I am terrified by this dark thing
That sleeps in me;
All day I feel its soft, feathery turnings, its malignity.

Clouds pass and disperse.
Are those the faces of love, those pale irretrievables?
Is it for such I agitate my heart?

I am incapable of more knowledge.
What is this, this face
So murderous in its strangle of branches?——

Its snaky acids hiss.
It petrifies the will. These are the isolate, slow faults
That kill, that kill, that kill.

Little poppies, little hell flames,
Do you do no harm?

You flicker. I cannot touch you.
I put my hands among the flames. Nothing burns

And it exhausts me to watch you
Flickering like that, wrinkly and clear red, like the skin of a mouth.

A mouth just bloodied.
Little bloody skirts!

There are fumes I cannot touch.
Where are your opiates, your nauseous capsules?

If I could bleed, or sleep! -
If my mouth could marry a hurt like that!

Or your liquors seep to me, in this glass capsule,
Dulling and stilling.

But colorless. Colorless.

I ordered this, clean wood box
Square as a chair and almost too heavy to lift.
I would say it was the coffin of a midget
Or a square baby
Were there not such a din in it.

The box is locked, it is dangerous.
I have to live with it overnight
And I can't keep away from it.
There are no windows, so I can't see what is in there.
There is only a little grid, no exit.

I put my eye to the grid.
It is dark, dark,
With the swarmy feeling of African hands
Minute and shrunk for export,
Black on black, angrily clambering.

How can I let them out?
It is the noise that appals me most of all,
The unintelligible syllables.
It is like a Roman mob,
Small, taken one by one, but my god, together!

I lay my ear to furious Latin.
I am not a Caesar.
I have simply ordered a box of maniacs.
They can be sent back.
They can die, I need feed them nothing, I am the owner.

I wonder how hungry they are.
I wonder if they would forget me
If I just undid the locks and stood back and turned into a tree.
There is the laburnum, its blond colonnades,
And the petticoats of the cherry.

They might ignore me immediately
In my moon suit and funeral veil.
I am no source of honey
So why should they turn on me?
Tomorrow I will be sweet God, I will set them free.

The box is only temporary.

Your clear eye is the one absolutely beautiful thing.
I want to fill it with color and ducks,
The zoo of the new

Whose names you meditate ---
April snowdrop, Indian pipe,
Little

Stalk without wrinkle,
Pool in which images
Should be grand and classical

Not this troublous
Wringing of hands, this dark
Ceiling without a star.
