In the fall of 2012 I often went to the architect Lorenzo Berna’s office in the morning to try to complete a picture, which would have been pleasantly spent between coffee and chatter. One morning when I arrived I found a Chinese priest who I already knew and who at that time was often studied by Lorenzo having commissioned him the drawings for a church to be built in Sichuan in China. While we chatted, Lorenzo proposed me to make some sketches for the large windows of the church. The idea took my mind for a few months, I thought about it while I was riding a scooter or walking with the dog. This totally new field intrigued me, above all the idea of working on transparencies and creating a work that had multiple levels of reading. Unfortunately the work was interrupted by the government of that province and the thing remained there.
