I testimoni delle Metafrasi dei Salmi di Manuele File. Isidoro di Kiev, Gerardo di Patrasso e il suo sodale Stamazio

The study presents a fresh philological, paleographical, and codicological assessment of the relationship between three main witnesses (Vat. gr. 16, Brit. Lib., Add. 17473 and Athon. Ivir. 165) of the reworking in political verses of the Psalms authored by the distinguished Palaeologan Byzantine poet Manuel Philes. The crucial role of Isidorus of Kiev, owner of the Vatican manuscript, is highlighted, as well as the fact that the copies of Vat. gr. 16 in the other two witnesses were carried out in succession by the prolific Pelopponnesian scribe Gerard of Patras and by his mate Stamatios, native of Crete but active as teacher at Corone in the Peloponnese.
