Cathédrales Hermétiques is the follow up of Cathédrales. In these series Aëgerter silkscreened photos of several churches with a thermal ink layer. The church interiors are revealed when exposed to sunlight, like photography in a dark room. This process takes about 30 minutes and just as long to return back to dark. With this work Aëgerter seeks for a meditative, and perhaps a spiritual, experience for the viewer.
Cathédrales hermétiques is the follow up to Cathédrales, and consists of a series that was born from the same starting point: a book published in the 1950s by the ministry of tourism to promote spiritual architecture in France. Moving away from the facades, Aëgerter selected three interiors over the scope of ten centuries to explore the different architectural modes of provoking a spiritual experience.
In this body of work, Aëgerter silkscreened three photographs of a Romanesque church (Saint-Benoit-sur-Loire, 10th century), a Gothic church (Coutances, 12th century) and a modern church (Sainte-Jeanne-d’Arc, Nice, 20th century) with a thermal ink layer: a black layer of ink reactive to the heat of the sun. In contrast to Cathédrales, these church interiors begin in darkness and are slowly revealed when exposed to sunlight, like photography in a darkroom; a cycle that takes about an hour. With this work, Aëgerter seeks for a meditative, spiritual experience for the viewer.
