Art restoration. Computers being used during the Mantegna Project, Padua, Italy, to reconstruct the Mantegna frescoes. Part of a fresco is seen on the screen. The 15th-century frescoes by Andrea Mantegna were smashed into tiny fragments by the bombs that destroyed the Church of the Eremitani, Padua, Italy, on 11 March 1944 during World War II. The fragments ranged in size from a cigarette packet to a stamp. Over 80,000 fragments have been preserved, and the Mantegna Project, since 2001, has been using a computer program to help position scans of the fragments on black-and-white photographs of the frescoes. Reproductions of the frescoes, and some of the original fragments, were placed on display in 2004.
