Famous quotes containing the word ages:

    “There is a relation between the hours of our life and the centuries of time. As the air I breathe is drawn from the great repositories of nature, as the light on my book is yielded by a star a hundred millions of miles distant, as the poise of my body depends on the equilibrium of centrifugal and centripetal forces, so the hours should be instructed by the ages and the ages explained by the hours.”
    —Ralph Waldo Emerson (1803–1882)

    “We, in the ages lying
    In the buried past of the earth,
    Built Nineveh with our sighing,
    And Babel itself with our mirth;”
    —Arthur William Edgar O’Shaughnessy (1844–1881)

    “Next time, to tarry,
    While the Ages steal—
    Slow tramp the Centuries,
    And the Cycles wheel!”
    —Emily Dickinson (1830–1886)
