A guiding force in German Expressionism, Ernst Ludwig Kirchner’s work has inspired subsequent generations of German artists such as Georg Baselitz. In this episode of Anatomy of an Artwork, find out about the influence of African sculpture on Kirchner’s representation of primitive nudes, learn about the artistic aims of Kirchner and his contemporaries in the Die Brücke movement, and discover objects in the painting recognisable from photographs of the artist’s studio. ‘Akt vor dem Spiegel (Nude at the Mirror)’ is a highlight of our upcoming Impressionist, Modern & Surrealist Art Evening Sale (4 February | London).
