Giovanni Ciparissiota e il Contra Nilum Cabasilam. L'autore e il suo testo

This paper focuses on the three main manuscripts of John Kyparissiotes’ Contra Nilum Cabasilam, one of most important treatises composed during the theological dispute between Palamas’ supporters and his opponents in the 14th century Byzantine Empire. A palaeographical and codicological analysis of these documents, Vat. gr. 704, Laur. Plut. 5.16 and Par. gr. 1246, makes it possible to follow the progressive elaboration of the work, which results from the notes and corrections inserted by the author himself. This study aims to shed light on the way Kyparissiotes handled the copying and composition of his writing, and to identify the scholarly circle, closely related to the author, where these manuscripts were copied.
