Famous quotes containing the words speckle and/or pattern:
“Leaves chase warm buses, speckle statued air,
Pile up in corners, fetch out vague broomed men
Through mists at morning.”
—Philip Larkin (1922–1986)
“It is a very true and expressive phrase, “He looked daggers at me,” for the first pattern and prototype of all daggers must have been a glance of the eye.... It is wonderful how we get about the streets without being wounded by these delicate and glancing weapons, a man can so nimbly whip out his rapier, or without being noticed carry it unsheathed. Yet it is rare that one gets seriously looked at.”
—Henry David Thoreau (1817–1862)
