Forty-six of these were detached folios, some of which had been removed from the same dispersed manuscript. Paintings and illuminations from fve intact manuscripts were also examined and analyzed, although not all of the individual works were included. The study was undertaken to better understand the materials and techniques used to create paintings and illuminations from the Islamic World, with particular attention paid to the diversity of greens, blues and yellows present. The research aimed to determine the full range of colorants, the extent of pigment mixing and the various preparatory drawing materials. The issue of binding materials was also addressed, albeit in a preliminary way. Keywords: Islamic manuscript, Islamic painting, XRF, Raman, FTIR, Imaging, Hyperspectral imaging Introduction project have been assigned to a particular town or region An ongoing interdisciplinary study at the Harvard Art and/or are well dated.
