Florence, February 20 - A piece of a 16th-century fresco that fell from the ceiling of a corridor in Florence's Uffizi Gallery on February 6 has been put back, Florentine museums chief Cristina Acidini said Wednesday. "The restoration achieved the expected results and the fresco is nicely back together," she said. The 30cm-diameter piece, depicting an allegorical female figurine, came off when a worker stepped through the floor from the storey above. It did not hit anyone. The ornamental fresco is not the work of any of the masters that have decorated the historic museum's halls, such as Michelangelo, Leonardo and Donatello.
