Argentinian artist Aimee Zito Lema created 12 sculptures made of cement mixed with photographic prints on paper. They were located behind the High Choir in the ambulatory. In Roman Catholic times, before the Reformation of 1578, statues of the 12 apostles hung from the pillars in the High Choir. These images were removed and/or destroyed, leaving only the empty spots on the pilasters. It is these traces of absence that inspired for creating this series of abstract sculptures. The photographs are infrared and X-ray documentation of the original pillars.
