Within the Château de Versailles, Eliasson has installed a series of “subtle space interventions” using mirrors and light. The curious museum (2010), consisting of mirrors placed behind the windows of the Hercules Room, reflects the room’s arches back at the visitor, while, at the end of the Hall of Mirrors, the reflective triangle of Your sense of unity (2016)—bisected by a semi-circle—conjures a multiplicity of illuminated circles. The artist’s delicate approach continues with Solar compression (2016), a suspended mirror that rotates, slowly, one edge of it emanating orange light. It reflects the marquetry of the wooden floorboards and the fireplace in the King’s Guards’ Room. The subtlest piece, though, is The gaze of Versailles (2016), two gold balls—alluding to Eliasson’s reading glasses—placed on a window pane in the Lower Gallery, looking out over the gardens.
