Methodologically, finding an answer to the main research question implies a conceptual turn from generalized definitions, such as the Middle Ages, Renaissance, realism, Platonism, Neoplatonism, etc., to the history of specific manuscripts and their material history in its dynamic interaction between author, editor, scribe, reader, and librarian, in close connection with which the history of relevant scientific and philosophical ideas is considered. More specifically, the project attempts first and foremost to clarify the extraordinary reception of the works of Nicholas of Cusa in the manuscripts from the Erfurt Charterhouse in the fifteenth century in the context of controversies about philosophical realism and individualization of experience-based knowledge which marked the contacts of Nicholas of Cusa with the fifteenth-century Erfurt Carthusians. Secondly, its essential part is the study of the World chronicle from Wrocław and preparation of its edition. This chronicle was written under the editorship of the Carthusian monk John Hagen de Indagine. It not only contains important and previously unpublished information about Nicholas of Cusa’s contacts with the Carthusians, but also marks a shift in Carthusian theoretical interest from pure mystical contemplation to the experience of contemplation of history that made itself felt in the second half of the fifteenth century. The main object of study must be collected manuscripts from libraries in Wrocław, Weimar, Eisleben, Berlin, Erfurt, Leipzig, Moscow, Uppsala, Budapest, Oxford.
