This website has been created to accompany an exhibition at the Library of Congress in December 2006. The exhibition focusses on a work by Leonardo da Vinci, commissioned in 1481 by the monks of San Donato a Scopeto near Florence for a wooden panel painting of an altar-piece celebrating the Adoration of the Magi. This exhibition displays a study from the Uffizi Gallery in Florence. Through images, multi-layered readings, infra-red reflectograms and accompanying information, the exhibition examines the details of both the preparatory drawing and painting. A movie from the Institute and Museum of the History of Science, Florence, Italy offers an analysis of the creative process that informed the Adoration of the Magi and a flash animation offers magnifications of the image.
