From the cubes sawed from the same limestones, I created the moon sculptures, on the surface of which were engraved the selenographies from the 17th to the 19th century. These sculptures were transformed into calcium oxide by firing them in a kiln at over 1,200 °C, giving them a new potential to glow when heated to over about 2,000 °C. They are the so-called “limelight”, an intense form of lighting that was used as theater lighting in the 19th century.
