The Mona Lisa Sprinkler Incident
When the Mona Lisa was borrowed by the USA in 1963, and made its way under heavy protection to Metropolitan Museum of Art.
“I dashed to the [storeroom] to study my gorgeous acquisition, only to find that Murray Pease, the head of the conservation studio, and his assistant Kate Lefferts, [and] the officials from the Louvre in charge of the Leonardo portrait were rushing around with towels,” writes Dr Hoving.
“No one ever discovered why, but some time during the night one of the fire sprinklers in the ceiling broke its glass ampoule and the masterpiece of painting had been…rained upon,” he adds.
Guards monitoring the Mona Lisa on a black-and-white monitor outside the storeroom could not see the water on their grainy screen.
“The Mona Lisa, according to the Louvre official, was okay…He told me that the thick glass covering it had acted like an effective…raincoat. The rainstorm was never mentioned to the outside world.” \
Henry Gentle, a London based private picture restorer, said damage to the painting could have been serious if it had not been protected by glass. “The paint could have swelled off [the panel] and become unstable. It really would have depended on the painting itself, whether it was protected by a strong varnish or not, and how long the water was dribbling on the surface.”
