Two of my favorites have already been listed–The Love Song of J. Alfred Prufrock and Do Not Go Gentle Into That Good Night .
Here are my other two favorites:
She Walks in Beauty by George Gordon, Lord Byron
She walks in beauty, like the night
Of cloudless climes and starry skies;
And all that’s best of dark and bright
Meet in her aspect and her eyes:
Thus mellow’d to that tender light
Which heaven to gaudy day denies.
One shade the more, one ray the less,
Had half impair’d the nameless grace
Which waves in every raven tress,
Or softly lightens o’er her face;
Where thoughts serenely sweet express
How pure, how dear their dwelling-place.
And on that cheek, and o’er that brow,
So soft, so calm, yet eloquent,
The smiles that win, the tints that glow,
But tell of days in goodness spent,
A mind at peace with all below,
A heart whose love is innocent!
AND
Pied Beauty by Gerard Manley Hopkins
Glory be to God for dappled things–
For skies of couple-colour as a brinded cow;
For rose-moles all in stipple upon trout that swim;
Fresh-firecoal chestnut-falls; finches’ wings;
Landsacpe plotted and pieced–fold, fallow, and plough;
And all trades, their gear and tackle and trim.
All things counter, original, spare, strange;
Whatever is fickle, freckled (who knows how?)
With swift, slow; sweet, sour; adazzle, dim;
He fathers-forth whose beauty is past change:
Praise him.
AND
The Suicide by Edna St. Vincent Millay but since it’s quite long I won’t type it in here.
