Rebecca Horn
"Three Graces Piano" (1994)

The German sculptor, performance artist and film-maker Rebecca Horn created a kinetic sculpture for the Bocken Hotel and Conference Centre that interprets the eternal theme of erotic desire in a playful and poetic way.

Three bottles, filled with the artist's favourite wines, three corks and four wine glasses embody male and female features, and slide up and down like pistons. They perform a kind of surreal, drunken ballet in which "they want to touch each other but cannot", says Rebecca Horn.

The title is a reference to the Graces in Roman mythology: the goddesses who always and repeatedly beguile the observer with their charm.
