A combination picture shows an original Giotto painting (L) and the same artwork under ultra-violet rays, exposing greater details, in the Peruzzi Chapel at the Santa Croce Church in Florence February 26, 2010. Restorers using ultra-violet rays have rediscovered rich original details of Giotto's paintings in the Peruzzi Chapel in Florence's Santa Croce church that have been hidden for centuries. The aim of the study, partly funded by a grant from the Getty Foundation in Los Angeles, was to gather information on the 170 square metre (1,830 square feet) chapel to use as a road map and "hospital chart" for a future restoration.
