Famous quotes containing the words blue and/or nature:

    “Dear Friend,
    the canebrakes
    nestled in the riverbank’s lap,
    their clusters broken
    from the weight of blue bees,
    have in time
    become stumps.”
    —Hla Stavhana (c. 50 A.D.)

    “We can paint unrealistic pictures of the juggler—displaying her now as a problem-free paragon of glamour and now as a modern hag. Or we can see in the juggler a real person who strives to overcome the obstacles that nature and society put in her path and who does so with vigor and determination.”
    —Faye J. Crosby (20th century)
