Famous quotes containing the word gallery:
“To a person uninstructed in natural history, his country or sea-side stroll is a walk through a gallery filled with wonderful works of art, nine-tenths of which have their faces turned to the wall. Teach him something of natural history, and you place in his hands a catalogue of those which are worth turning round.”
—Thomas Henry Huxley (1825–95)
“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)
“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)
