In Situ

This piece was created to commemorate the bicentenary of independence of Troinex, a commune near Geneva. The constellations engraved on the glass represent those that were visible in the night sky of 20 May 1817. The piece is placed so that every 20 May, the sun shines through the glass, tracing a curve on the ground around a basalt slab inscribed with the 1817 decree.
