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 was her stern necessity: all things
Are of one pattern made; bird, beast, and flower,
Deceive us, seeming to be many things,
And are but one. Beheld far off, they differ
As God and devil; bring them to the mind,
They dull its edge with their monotony.”
—Ralph Waldo Emerson (1803–1882)
