most well-known works, The Land of the Lotus Eaters (1861). In Europe, his work was well received and the prestigious London Art Journal declared him a master of landscape painting. In the winter of 1866–1867, Duncanson returned to Cincinnati. Inspired by his European travels, he painted many scenes of the Scottish landscape. Duncanson's time in Canada and the United Kingdom allowed him to gain even greater recognition in the international art scene. Ellen's Isle, Loch Katrine, 1871 This painting was inspired by a selection from Scottish writer Sir Walter Scott's 1810 poem, The Lady of the Lake. The narrative poem was important to several important contemporary African American leaders, such as W.E.B. Du Bois and Frederick Douglass. Art historian Joseph D. Ketner considers Ellen's Isle, Loch Katrine to be the "pinnacle of [Duncanson's] aesthetic and technical accomplishments." The work shows Duncanson's use of the conventions of Hudson River School artists, as well as his own romantic vision for landscape painting. Final years Throughout his career, Duncanson's works had always tended toward the pastoral, and his late works continued to show his love of landscape painting and resonated calmness and serenity.(p. 157) In the final years of his life, Duncanson developed dementia, possibly from lead poisoning. The dementia, and possibly schizophrenia, caused Duncanson to act unpredictably and erratically. He developed a belief in spiritualism and was convinced that he was possessed by a master painter. While Duncanson continued to create artwork, his behavior and declining physical health was alarming to his patrons. In 1872, Duncanson suffered a seizure while setting up an exhibition in Detroit, which eventually led to his death. Duncanson died on December 21, 1872; he was 51 years old. He was buried at the Woodland Cemetery in Monroe, Michigan. Legacy Robert Seldon Duncanson was one of few African American landscape painters of the nineteenth century, and he achieved levels of success unknown to his contemporaries. By the 1860s, Duncanson was proclaimed to be the "greatest landscape painter in the West" by the American Press and London newspapers held him in equal regard to other British artists at the time. Richard Powell of American Visions says that Duncanson’s success is a “victory over society’s presumptions of what African-American artist should create.” Duncanson became nationally and internationally known for his landscape paintings modeled after the Hudson River School tradition, and is credited with developing the regional Ohio River Valley art
