Famous quotes containing the word gallery:

    I should like to have seen a gallery of coronation beauties, at Westminster Abbey, confronted for a moment by this band of Island girls; their stiffness, formality, and affectation contrasted with the artless vivacity and unconcealed natural graces of these savage maidens. It would be the Venus de’ Medici placed beside a milliner’s doll.
    Herman Melville (1819–1891)

    It doesn’t matter that your painting is small. Kopecks are also small, but when a lot are put together they make a ruble. Each painting displayed in a gallery and each good book that makes it into a library, no matter how small they may be, serves a great cause: accretion of the national wealth.
    Anton Pavlovich Chekhov (1860–1904)

    I never can pass by the Metropolitan Museum of Art in New York without thinking of it not as a gallery of living portraits but as a cemetery of tax-deductible wealth.
    Lewis H. Lapham (b. 1935)
