Famous quotes containing the word stroke:
“So was produced this tragedy
In a far tower of ivory
Where, O young men, late in the night
All you who drink light and stroke the air
Come back, seeking the night, and cry
To strict Rapunzel to let down her hair.”
—Allen Tate (1899–1979)
“I should like to suggest that at least on the face of it a stroke by stroke story of a copulation is exactly as absurd as a chew by chew account of the consumption of a chicken’s wing.”
—William Gass (b. 1924)
“Fair maid, white and red,
Comb me smooth, and stroke my head;
And every hair a sheave shall be,
And every sheave a golden tree.”
