Famous quotes containing the word history:
“The history of the Victorian Age will never be written: we know too much about it.”
—Lytton Strachey (1880–1932)

—Henry David Thoreau (1817–1862)
“Perhaps universal history is the history of the diverse intonation of some metaphors.”
—Jorge Luis Borges (1899–1986)
