comes from years of research in the Frari Archives, in the Marciana Library and in Correr Museum. Between old shelves, turning the pages of ancient Buste, Raspe, Commentarii, I could taste the emotion of touching manuscripts, with signatures and seals of Procuratori, Dogi, Condottieres... I transcribed the many interesting things I have discovered part on books, others on slide-shows, others more are just laying as simple notes on my personal archives.
