Famous quotes containing the word stain:
“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)
“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)
“She comes to meet death,
To stain the altar of the goddess,
To hold her girl-throat
Toward the knife-thrust.”
—Hilda Doolittle (1886–1961)
