This exhibition catalogue offers fresh and nuanced perspectives on the intersections of art and esotericism, illuminating the often-overlooked roles of artist women in modern art history. The articles by international experts expand on the themes of the Ateneum Art Museum's groundbreaking exhibition Arcana Borealis: Northern Women and Esotericism. They examine how esotericism, mysticism, and alternative spirituality have been intertwined with the artistic practices of northern women from the late 19th century onward. By tracing the engagement of around fifty artist women with esoteric ideas and practices, the catalogue reveals how they expand the horizons of modernism and transform our understanding of art.
