Famous quotes containing the word gallery:
“Each morning the manager of this gallery substituted some new picture, distinguished by more brilliant or harmonious coloring, for the old upon the walls.”
—Henry David Thoreau (1817–1862)
“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 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)
