The title “Vocabularium architecturæ ædificatoriæ” could be translated into “Architectur of building architecture”. This book makes it easier for everybody to read or write about architecture. The book is well-ordered from “a” to “z”, like any ordinary dictionary. There aren’t any illustrations for better explanation of words. This would have probably taken up too much space, especially because the book is already rather thick. The general size makes it impractical to use it as a handbook. It is useful for understanding other non-fiction books. Thus, it is an encyclopaedia for true lovers. Ornamentation is found here only for new letters and on page breaks. This makes for more order, which is crucial if we talk about a lexicon. It also makes sense, that the entire book has the same layout, with the same writing and same size. There are even cross references, which he wrote in cursive. In his references you will often find names such as Vitruvius. This too is most interesting for people who have access to library with a number of books about architecture. You could read the named books if you were interested or at least the names could be familiar, which makes the whole thing more interesting. Carolo de Aquino seems to have been a Spanish monk. His name also includes books on history and agriculture, from which it can be concluded that the author did not deal practically with architecture but collected and arranged much more knowledge from various books. This book is only addressed at people who have access to literature about architecture. Else you couldn’t gain any knowledge from the book.
