Famous quotes containing the word stain:
“For wisdom is the property of the dead,
A something incompatible with life; and power,
Like everything that has the stain of blood,
A property of the living; but no stain
Can come upon the visage of the moon
When it has looked in glory from a cloud.”
—William Butler Yeats (1865–1939)
“Then suddenly the noon turns afternoon
And afternoon like an ill-written page
Will fade, until the very stain of light
Gathers in all the venom of the night
The equilibrium of the thirtieth age.”
—Allen Tate (1899–1979)
“The nightingales are singing near
The Convent of the Sacred Heart,
And sang within the bloody wood
When Agamemnon cried aloud,
And let their liquid siftings fall
To stain the stiff dishonored shroud.”
—T.S. (Thomas Stearns)
