The 13th century fresco of the Madonna dell'Arco di San Callisto in Trastevere was tagged with a graffiti artist's signature on March 18th. Locals were outraged to discover a white signature across the beloved image. A suspect was arrested in early April.
"I condemn the gesture, an expression of ignorance and disrespect towards the city and those who live there," declared the deputy mayor of Rome, Luca Bergamo.
