Famous quotes containing the word period:

    “Of all the barbarous middle ages, that
    Which is most barbarous is the middle age
    Of man! it is—I really scarce know what;
    But when we hover between fool and sage,
    And don’t know justly what we would be at—
    A period something like a printed page,
    Black letter upon foolscap, while our hair
    Grows grizzled, and we are not what we were.”
    —George Gordon Noel Byron (1788–1824)
