This undated picture made available by the by the National Geographic, shows work on the search for Leonardo da Vinci's "The Battle of Anghiari" project, conducted in Florence's Palazzo Vecchio.The project is led by the National Geographic Society and University of California San Diego's Center of Interdisciplinary Science for Art, Architecture and Archaeology (CISA3), in cooperation with the City of Florence.
