Black Rook in Rainy Weather-Sylvia Plath
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. -
Morning Song-Sylvia Plath
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. -
Mirror-Sylvia Plath
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. -
Elm-Sylvia Plath
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.
