The seminar explores the cultural history of Europe from the 9th to the 12th c. and the emergence of a cultural convergence that allowed to imagine the Latin West as the Latin West. Our window into this process is the codification of various subjects in books and libraries and in the collection, arrangement and transmission of history books, legal handbooks, patristic, hagiographical or liturgical collections. In so doing the course introduces students to paleography, codicology, basic techniques of editing texts and the study of Latin manuscripts, scriptoria and libraries.
