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)
“... the histories of Blacks and Jews in bondage and out of bondage, have been blood histories pursued through our kindred searchings for self-determination. Let this blood be a stain of honor that we share. Let us not now become enemies to ourselves and to each other.”
—June Jordan (b. 1936)
“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)
