Famous quotes containing the word mantle:

    There are a sort of men whose visages
    Do cream and mantle like a standing pond,
    And do a willful stillness entertain,
    With purpose to be dressed in an opinion

    As who should say, “I am Sir Oracle,
    And when I ope my lips let no dog bark!”
    William Shakespeare (1564–1616)
