La Vita Procli di Marino di Neapoli fra Niceforo Gregora e Bessarione. Appunti sul Laur. Plut. 86.3, con osservazioni sulla storia del testo del De Pythagorica secta di Giamblico in età umanistica

Cardinal Bessarion penned a short epitome of Marinus’ Life of Proclus in the Monacensis 547. This paper, offering a new edition and Italian translation of the text, aims to demonstrate that the Cardinal read Marinus’ Life of Proclus on the Laur. Plut. 86.3, a late 13th century manuscripts annotated by the byzantine scholar Nikephoros Gregoras. This finding sheds light on the transmission of the Pythagorean works of Jamblichus and on the production of Theodore the Deacon, an early 15th century scribe whose activity and chronology remain still somewhat obscure. The last part of the study offers a new piece of evidence on Theodore’s role in the transmission of Polybius (Vat. gr. 124).
