Chapter 13.5: Issues of Restoration and Conservation
Artlex provides the following definition of art restoration – The work of repairing damage to artworks, bringing them back to their original condition. Unlike art conservation, this can admit the addition of elements that were not actually pieces of the original, but which are known to look just like them. Restoration techniques are used in recreating a portion of a painting that is damaged or missing, for instance. Focus on the differences between restoration and conservation.

Sistine Chapel Restoration
The Sistine Ceiling had been damaged by centuries of accumulated smoke (400 years of being lit by oil lamps and candles), cracked and falling materials, and several previous restorations of dubious quality, when it was painstakingly conserved and restored in the 1990s. The photos below show the figure of the Prophet Daniel before and after this restoration work was done.
Restoring a work of art means that changes in the visual appearance of the work will occur. Frequently, change brings controversy and divergent points of view. Two of the most hotly contested restorations in the past 15 years have centered around works of art by two of the most famous artists in Western culture: Michelangelo and Leonardo da Vinci. Pinin Brambilla Barcilon is the restorer in charge of the famous restoration of The Last Supper by da Vinci. Big Think’s article on the critics of the Sistine restoration gives us a view into the controversies surrounding the twelve-year restoration of the Sistine Ceiling by Michelangelo.

Resources for Ethical Issues in Art Restoration:
- World Monuments Fund at Angkor Wat: Churning of the Ocean of Milk Gallery At the magnificent temple of Angkor Wat, World Monuments Fund is restoring the Churning of the Sea of Milk Gallery. Rainwater and harmful salts have leaked through the roof of the gallery, which forms the south half of Angkor Wat’s prominent east facade, damaging the fragile surface of the frieze. Without treatment, the deterioration will increase at an alarming rate, risking the eventual loss of what most historians regard as the most ambitious and finely produced stone sculptures in Khmer art.
