Famous quotes containing the word day:
“The consolations of space are nameless things.
It was after the neurosis of winter. It was
In the genius of summer that they blew up
The statue of Jove among the boomy clouds.
It took all day to quieten the sky
And then to refill its emptiness again....”
—Wallace Stevens (1879–1955)
