The treatises of Maggi and Castriotto, Lorini and Teti were all published in the second half of the sixteenth century between 1564 and 1596. They are the testimony of a new kind of specialized technical writing, born out of the evolution of the war techniques that forced the builders to review and modify the existing fortifications and to develop new models.
The spread of artillery changed the division of competences between architects and military engineers and also influenced the change of the shape of cities.
Ruggieri's work demonstrates the interest in a very different sector, that of representing civil architecture through relief and graphic rendering. A work of this type (Studio d'architettura civile … Opera de' più celebri architetti de nostri tempi, 1702-1721) was published in Rome by Domenico De Rossi, who had illustrated Rome's palaces and churches, adding examples of Neapolitan, Milanese and Florentine architecture.
Another example comes from France: Jean Mariette's L'architecture française, published in Paris in 1727, a work also consisting solely of plans, sections and elevations of buildings, especially Parisian ones.
Ruggieri documented exclusively Florentine architecturs, almost all ofit built in the sixteenth century, with some works from the beginning of the 17th century.
