Famous quotes containing the word canon:
“O! that this too too solid flesh would melt,
Thaw and resolve itself into a dew;
Or that the Everlasting had not fix’d
His canon ‘gainst self-slaughter! O God! O God!
How weary, stale, flat, and unprofitable
Seem to me all the uses of this world.
Fie on’t! O fie! ‘tis an unweeded garden,
That grows to seed;”
—William Shakespeare (1564–1616)
