Famous quotes containing the word century:

    When her husband clutches at her dress,
    she lowers her face,
    her modesty aroused.
    When he wants a wild embrace,
    she shyly secrets away
    her limbs.
    She can’t say a word
    and bestows her gaze
    on her beaming friends.
    A new wife suffers
    with shame
    the first time she makes love.
    Amaru (c. seventh century A.D.)
