In Lumière fossile, the presence of real fossils explicitly evokes transparent maps of imaginary skies.

Constructions forming fragile maps of the sky in four dimensions of space and time, where the constellations are represented by lengths of welded piano wire linking fossilised stars, pentacrinoids, stuck to the structure. These small star-shaped fossils 200 million years old are marine animals known as sea lilies.

The artist collected them as a child in the Jura vineyards near the studio where he lives. In these constructions, the idea of fossil radiation and the time that has passed since the universe began is made tangible, informed by geological time in comparison with the date when the work was made.
