I came across your post, while I was searching for ‘columns’.
The title of my book is “Della architettura” written by Viola Zanini in 1677.
Both books are written by Italian Architects and lived around the same time.
In my Book Zanini shows us the new symmetry of the five principles. He does this with the help of geometry and a lot of small illustrations throughout the book. Therefore both thematize the classical orders and and illustrate them with several drawings. The column is looked at more closely and very accurately drawn and depicted at different significant architectural periods. For example, you can clearly see how the column has evolved from a simple straight, solid stone column, as with the Greeks, to a beautiful, filigree decorated column with the Romans. As you also mentioned that the dimensions of your book are rather larger, this coincides with mine which was very heavy and thick.
Giovanni Battista was Born in Venice. He works as an archaeologist who lived his Major Part of his life in Rome. Zanini was born in Padua, only a few kilometers away. Battista was the son of a stonemason who also worked as a construction manager. Zanini came from a family of master builders: his grandfather was a mason and his father worked in the building trade in the city of Padua in the last decades of the 16th century. Zanini lived from 1575-1631 and Battista from 1720-1778, so around 150 years later.
Both books receive explanations of architectural elements, such as a chapter on capitals and entablatures. My book contains numerous copper engravings. These are supplemented with relatively little text. Much is illustrated and explained by detailed technical drawings. Zanini also uses examples of different types of cornices to illustrate. The theory can thus be understood more easily through the visual implementation.
