Famous quotes containing the words image and/or gallery:
“The places we have known do not only belong to the world of space in which we situate them for the sake of simplicity. They were but a thin slice between contiguous impression which formed our lives back then; the memory of a certain image is but the regret of a certain instant; and the houses, the roads, the avenues are fleeting, alas! as the years.”
—Marcel Proust (1871–1922)
“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)
