Kirchner was particularly inspired by the naked human body, especially the female nude. Whether in the studios in Dresden, Berlin and Davos, or at the Moritzburg ponds, on the beaches of the island of Fehmarn and in the forests of Davos, Kirchner repeatedly depicted Erna, his partner and permanent muse, models, friends who came to visit, dancers and farmers' daughters, and was inspired by their naked skin to create wonderful compositions. What is more immediate than the naked body for the representation of natural movement? He will certainly have been regarded as an eccentric, especially in Davos.

Lying, sitting, standing or kneeling, they present themselves to the viewer and never seem artificial in their posture, as if a moment of movement is always captured. At the toilet, at the hairdressing, at washing, at swimming, at dancing, at playing, at sports, resting or entertaining.
