Famous quotes containing the word stain:
“She comes to meet death,
To stain the altar of the goddess,
To hold her girl-throat
Toward the knife-thrust.”

“No more be grieved at that which thou hast done,
Roses have thorns, and silver fountains mud,
Clouds and eclipses stain both moon and sun,
And loathsome canker lives in sweetest bud.
All men make faults, and even I in this,
Authorizing thy trespass with compare,
My self corrupting salving thy amiss,
Excusing thy sins more than thy sins are:”
—William Shakespeare (1564–1616)
“As for me, Abraham, Isaac, and Jacob are now only the subtlest imaginable essences, which would not stain the morning sky.”
—Henry David Thoreau (1817–1862)
