Famous quotes containing the word pattern:

    Put out the light, and then put out the light.
    If I quench thee, thou flaming minister,
    I can again thy former light restore
    Should I repent me; but once put out thy light,
    Thou cunning’st pattern of excelling nature,
    I know not where is that Promethean heat
    That can thy light relume.
    William Shakespeare (1564–1616)
