Famous quotes containing the words cloud and/or base:
“Let chaos storm!
Let cloud shapes swarm!
I wait for form.”

“Then must you speak
Of one the lov’d not wisely but too well;
Of one not easily jealous, but, being wrought,
Perplex’d in the extreme; of one whose hand,
Like the base Indian, threw a pearl away
Richer than all his tribe;”
—William Shakespeare (1564–1616)
