The Mirror Poem by Dante Gabriel Rossetti

SHE knew it not:—most perfect pain
To learn: this too she knew not. Strife
For me, calm hers, as from the first.
'Twas but another bubble burst
Upon the curdling draught of life,—
My silent patience mine again.
As who, of forms that crowd unknown
Within a distant mirror's shade,
Deems such an one himself, and makes
Some sign; but when the image shakes
No whit, he finds his thought betray'd,
And must seek elsewhere for his own.
