The book has a total of 39 pages. Most of the 94 chapters are quite short. Sometimes they only consist of single sentences. Each chapter deals with a very specific topic. Such topics are on the one hand the topography of Rome, the city itself, the buildings and monuments of Rome (since my name ist Titus, it made me smile that on page 15 he speaks of the Titus Arch in Rome). On the other hand, Pirro Ligorio also talks about the social and political institutions of ancient Rome and shares the everyday life of the Roman people and talks about their customs.
On one of the first pages you can find the “Exlibris coat of arms”. This is the only illustration in the book. I was told during my visit that the decision to abandon illustrations was probably made for economic reasons.
The book is very small and its size comes close to the standard Octodecimo format: height: 161mm, width: 160mm and width: 14mm. The book appears in a good condition and shows some signs of use. Individual pages are slightly torn at the corners or have smaller stains.
