### Famous quotes containing the word skein:

Like a skein of loose silk blown against a wall
She walks by the railing of a path in Kensington Gardens,
And she is dying piecemeal
of a sort of emotional anemia.
Ezra Pound (1885–1972)

I—love’s skein upon the ground,
My body in the tomb—
Shall leap into the light lost
In my mother’s womb.
William Butler Yeats (1865–1939)
