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 (17571827)
“The highest perfection of politeness is only a beautiful edifice, built, from the base to the dome, of ungraceful and gilded forms of charitable and unselfish lying.”
—Mark Twain [Samuel Langhorne Clemens] (18351910)
