Mount Monadnock loomed large in the consciousness of American painter Abbott Thayer (1849-1921). Not only did he paint a number of intense landscapes of the mountain, but he was also active in the effort to establish Monadnock State Park. Thayer's art combines the classical ideals of European painting (he studied under Jean-Léon Gérôme in Paris) with a strong scientific outlook (he made impressive studies in animal camouflage) and a transcendentalist spirit inherited from Ralph Waldo Emerson. As far as I know, he created five paintings of Mount Monadnock (not counting his Monadnock Angel): ca. 1889, ca. 1911, after 1911, in 1917, and ca. 1917.
