This work, as rare as it is well known, of the genealogist Im-hoff is of particular interest to Italy; in fact, it illustrates the coats of arms and genealogies of 20 of the most famous of the Italian noble families: among the reigning families are the Cybo, dukes of Massa and princes of Carrara, the Farnese dukes of Parma and Piacenza, Pico duke of Mirandola and Concordia, and Medici, grand dukes of Tuscany and princes of Ottajano; but the volume also includes the Milanese Biraghi (who are also Piedmont in origin), Homodei and Trivulzio (Gallio Trivulzio), the Sfondrati of Cremona (the family of Pope Gregory XIV), the Ferrero of Masserano from the Piedmont, the Tuscan (counts) Guidi, Piccolomini, Salviati and Strozzi, the powerful and domineering Roman families Orsini and Colonna, with their numerous branches in the Kingdom of Naples, where flourished the Giudice family, princes of Cellamare and dukes of Giovinazzo (but of Genoese extraction), the Neapolitan Pignatelli and Gambacorta, the powerful Sanseverino, and the Ruffo of Calabria. The volume concludes with a curious genealogy of a Belgian branch of the Milanese Visconti.
