After nearly 50 years of separation, the five wooden panels that make up Giorgio Vasari's monumental Last Supper painting (more than 8 by 21 feet) were reassembled following an international conservation effort at the Opificio delle Pietre Dure (OPD) in Florence supported by the Getty Foundation. As part of the Panel Paintings Initiative, the Foundation provided a major training grant to the OPD to treat Vasari's multi-panel painting, one of the most severely damaged artworks to survive the disastrous Florence Flood of 1966. Since the artwork was submerged in water for over 12 hours, it required immediate separation of the individual panels to hasten drying. Conservators also applied an emergency paper treatment to the surface to prevent paint from simply peeling away from its sodden wooden support. Due to the enormous complexity of these conservation challenges, it was only decades later that experts developed the technology to repair and rejoin the painting.
Starting in 2010, conservators of all skill levels benefited from side-by-side training with leading OPD experts and participated in all phases of this complex structural treatment. Together the team developed a conservation solution based on the support system originally devised by Vasari himself, which stabilized the painting and also allowed the wooden panels to move naturally with standard temperature and humidity fluctuations. The team was also able to recover an unanticipated amount of the original painted surface, revealing the artist's hand in surprising detail.
Once the individual panels were rejoined with a secure and lasting support, the OPD completed a final conservation of the surface of the painting in time to return the Last Supper to public view for the 50th anniversary of the flood on November 4, 2016. The finished results were on view in a joint exhibition with the OPD and the Museo dell'Opera di Santa Croce, and a book on the conservation process, Structural Conservation of Panel Paintings at the Opificio delle Pietre Dure in Florence: Method, Theory, and Practice was published in 2017.
