I inform you that a large exhibition on ancient glass and science entitled Vitrum. Il vetro fra arte e scienza nel mondo romano (http://brunelleschi.imss.fi.it/vitrum/) had opened on March 27 in Florence at Palazzo Pitti. Several scientific instruments, including Archimede’s model of the universe, have been reconstructed. While the catalogue of the exhibition is in Italian (http://www.giunti.it/index.php3?SCREEN=libro&SCHEDA=1&sid=1FgOnGUzWSq0wMgp9eeSxrRv7fOKunvv) a complementary publication entitled When Glass Matters. Studies in the History of Science and Art from Graeco-Roman Atniquity to Early Modern Era (edited by Marco Beretta), Florence, Leo S. Olschki (www.olschki.it), explores a the same topic on a longer period.

All best, Marco Beretta Professor of History of Science at the University of Bologna Vice-Director Istituto e Museo di Storia della Scienza Piazza dei Giudici 1 50122 Firenze Italy
