“She exhibited with Mackintosh at the 1900 Vienna Secession, where she was an influence on the Secessionists Gustav Klimt and Josef Hoffmann. They continued to be popular in the Viennese art scene, both exhibiting at the Viennese International Art Exhibit in 1909.”

“Mackintosh did not keep sketchbooks, which reflects her reliance on imagination rather than on nature. A few sources provided significant inspiration for her works, including the Bible, the Odyssey, poems by Morris and Rossetti, and the works of Maurice Maeterlinck. Her works, along with those works of her often collaborating sister, defied her contemporaries’ conceptions of art. Gleeson White wrote, “With a delightfully innocent air these two sisters disclaim any attempt to acknowledge that Egyptian decoration has interested them specially. ‘We have no basis.’ Nor do they advance any theory.” The beginning of her artistic career reflects broad strokes of experimentation. Largely drawing from her imagination, she reinterpreted traditional themes, allegories, and symbols in inventive ways. For instance, immediately following the 1896 opening of her Glasgow studio with her sister, she transformed broad ideas such as “Time” and “Summer” into highly stylized human forms. Many of her works incorporate muted natural tones, elongated nude human forms, and a subtle interplay between geometric and natural motifs. Above all, her designs demonstrated a type of originality that distinguishes her from other artists of her time.”
