This summer the Institute welcomes Reverend Canon Doctor Federico Gallo to lecture on "On Diplomatics: The Science of Reading Medieval Documents." Rev. Can. Dr. Gallo, of the Archdiocese of Milan, studied Classics at the Università Cattolica del S. Cuore di Milano. He went on to serve in the Vatican Secret Archives, working in Latin and Greek Paleography, Diplomatics, and Archival Studies, and in the Archivio Storico Diocesano di Milano. Since 2008 he has been Dottore of the Biblioteca Ambrosiana, where he is Director of the Department of Classics (Classe di Studi Greci e Latini dell'Accademia Ambrosiana) and of the Library. There, he organizes conferences, publications, and research and is responsible for the daily life of the Library and its readers. His publications focus on the history of libraries, manuscripts, ancient collections in libraries and archives, and the history of the Biblioteca Ambrosiana. This lecture on his research follows those at the Medieval Institute in 2013 and 2015.
