Famous quotes containing the words cloud and/or base:

    Follow your saint, follow with accents sweet;
    Haste you, sad notes, fall at her flying feet.
    There, wrapped in cloud of sorrow, pity move,
    And tell the ravisher of my soul I perish for her love.
    Thomas Campion (1567–1620)

    I have always heard, Sancho, that doing good to base fellows is like throwing water into the sea.
