Famous quotes containing the words reference and/or clock:

    “These roses under my window make no reference to former roses or to better ones; they are for what they are; they exist with God to-day. There is no time to them. There is simply the rose; it is perfect in every moment of its existence.”
    —Ralph Waldo Emerson (1803–1882)

    “What brought them there so far from their home,
    Cuchulain that fought night long with the foam,
    What says the Clock in the Great Clock Tower?
    Niamh that rode on it; lad and lass
    That sat so still and played at the chess?
    What but heroic wantonness?”
    —William Butler Yeats (1865–1939)
