Résumé :
The manuscript Barb. gr. 535 is a Trimenaeum for the months of September,
October, and November, completed on July 24, 1556, by the scribe Georgios
Basilikos and commissioned by the clergy of the cathedral of Bova (Calabria), the last
Italo-Greek bastion. A note written in the Barb. gr. 535 documents the passage of the
episcopal church of Bova on November 23, 1572, from the Byzantine rite to the Latin
one. The present article provides an analytical description of the manuscript, including
the texts within and its codicological and palaeographical aspects. The appendix at the
end attempts to understand when the two Trimenaea Barb. gr. 535 and 543 (immediate
continuation of the former) were attested in the Barberini’s book collection and how
they were entered, based on an investigation of some manuscript catalogues of the
Barberini family’s library
