“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)
“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)
