Famous quotes containing the word dross:
“At fifteen one is first beginning to realize that everything isn’t money and power in this world, and is casting about for joys that do not turn to dross in one’s hands.”
—Robert Benchley (1889–1945)
“Was this the face that launched a thousand ships,
And burnt the topless towers of Ilium?
Sweet Helen, make me immortal with a kiss.—
Her lips suck forth my soul; see where it flies!—
Come, Helen, come, give me my soul again.
Here will I dwell, for heaven be in these lips,
And all is dross that is not Helena.”
—Christopher Marlowe (1564–1593)
