Famous quotes containing the words oil and/or red:
“No skilled hands
caress a stranger’s flesh with lucid oil before
a word is spoken
no feasting
before a tale is told, before
the stranger tells his name.”
—Denise Levertov (b. 1923)

For the black vision and tangle in her brains,
Nor is there knowing soever in the city
Of the red histories that throbbed in her blue veins.””
