Le Sommeil, Thérésou
In the storerooms of the Petit Palais museum in Paris, Aëgerter happened upon 19th-century daguerreotypes by Léon Riesener, including a touching image of his sleeping daughter Thérèse. It inspired her to create a lithophane, a process discovered by the artist during her residency at the Manufacture de Sèvres.
The 6mm moulded large porcelain plate is traversed and illuminated by light, revealing the image as a negative of the photograph. The image in slight relief appears and disappears depending on the time of the day, reminiscent of the sleep cycle.
