Famous quotes containing the words cloud and/or base:
“On a cloud I saw a child,
And he laughing said to me,
“Pipe a song about a Lamb”;
So I piped with merry chear.
“Piper pipe that song again”—
So I piped, he wept to hear.
“Drop thy pipe thy happy pipe
Sing thy songs of happy chear”;
So I sung the same again
While he wept with joy to hear.”
—William Blake (1757–1827)
“In the land of turkeys in turkey weather
At the base of the statue, we go round and round.
What a beautiful history, beautiful surprise!
Monsieur is on horseback. The horse is covered with mice.”
—Wallace Stevens (1879–1955)
