Famous quotes containing the words points and/or triple:

    Mankind is not a circle with a single center but an ellipse with two focal points of which facts are one and ideas the other.
    Victor Hugo (1802–1885)

    And we fairies, that do run
    By the triple Hecate’s team

    Following darkness like a dream,
    Now are frolic. Not a mouse
    Shall disturb this hallowed house.
    William Shakespeare (1564–1616)
