The drawings discussed in this book, published in association with the British Museum, were included in the exhibition,�Fra Angelico to Leonardo: Italian Renaissance Drawings, held at the British Museum, London and the Uffizi Gallery, Florence in 2010-2011. Technical studies of 47 of the British Museum's finest Italian Renaissance drawings are given based on non-invasive and non-contact examination and analysis. Great emphasis has been placed on how the results from such examination and analysis can be interpreted in a manner that goes beyond simply determining the materials employed by artists, to draw conclusions about their role in the Renaissance workshop and the patterns of use across fifteenth-century Italy.
