Thirteen Ways of Looking at a Blackbird by Wallace Stevens

I

Among twenty snowy mountains,
The only moving thing
Was the eye of the blackbird.

II

I was of three minds,
Like a tree
In which there are three blackbirds.

III

The blackbird whirled in the autumn winds.
It was a small part of the pantomime.

IV

A man and a woman
Are one.
A man and a woman and a blackbird
Are one.

V

I do not know which to prefer,
The beauty of inflections
Or the beauty of innuendoes,
The blackbird whistling
Or just after.

VI

Icicles filled the long window
With barbaric glass.
The shadow of the blackbird
Crossed it, to and fro.
The mood
Traced in the shadow
An indecipherable cause.

VII

O thin men of Haddam,
Why do you imagine golden birds?
Do you not see how the blackbird
Walks around the feet
Of the women about you?

VIII

I know noble accents
And lucid, inescapable rhythms;
But I know, too,
That the blackbird is involved
In what I know.

IX

When the blackbird flew out of sight,
It marked the edge
Of one of many circles.

X

At the sight of blackbirds
Flying in a green light,
Even the bawds of euphony
Would cry out sharply.

XI

He rode over Connecticut
In a glass coach.
Once, a fear pierced him,
In that he mistook
The shadow of his equipage
For blackbirds.

XII

The river is moving.
The blackbird must be flying.

XIII

It was evening all afternoon.
It was snowing
And it was going to snow.
The blackbird sat
In the cedar-limbs.

Wallace Stevens

Wallace Stevens (October 2, 1879 – August 2, 1955) was an American modernist poet. He was born in Reading, Pennsylvania, educated at Harvard and then New York Law School, and spent most of his life working as an executive for an insurance company in Hartford, Connecticut. He won the Pulitzer Prize for Poetry for his Collected Poems in 1955.
Stevens's first period of writing begins with the 1923 publication of Harmonium, followed by a slightly revised and amended second edition in 1930. His second period occurred in the 11 years immediately preceding the publication of his Transport to Summer, when Stevens had written three volumes of poems including Ideas of Order, The Man with the Blue Guitar, and Parts of a World, along with Transport to Summer. His third and final period began with the publication of The Auroras of Autumn in the early 1950s, followed by the release of his Collected Poems in 1954, a year before his death.

Some of his best known poems are:
