Un inedito opuscolo greco autografo di Ciriaco d'Ancona sulle antiche magistrature romane

MS Milan, Bibliotheca Ambrosiana Q 13 sup., the product of 12 scribes and written on papers with watermarks, was probably written in Bessarion's circle in Rome but using material from Mistra. At the end an autograph bifolium, not previously noticed, of Ciriaco d'Ancona contains an unpublished text in Greek on the ancient Roman constitution; this is printed with an analysis of the sources.
