The structure of the book assigned to me, Delle fortificazioni di Buonaiuto Lorini, nobile fiorentino, is very light and clear. It begins with an index written in double columns which, afterwards, gives space to the text presented in one unique column. The headings are showy, as they probably meant to help the reader throughout the text. In fact, their font size is much bigger if compared to the text itself. The margins are wide as they contain little descriptions of the content being analyzed. Even at first sight, we understand that images play an important role: in terms of space, they cover almost half of the pages. We can conclude that text and images have the same importance and are both necessary in order to fully get the content.
Concerning the illustrations, in the first part we mostly find geometric forms along with their mathematical descriptions. Afterward, these forms are applied to architectural drawings like isometric views, planes and detail views. In fact, the images are meant to show and understand the practical part of the masterpiece.
As for the organization of the images, we find different types of approaches: initially, there is list of geometric forms; then, images cover the entire page or even the two pages. The cases in which they come in-text are rarer, but even here, the text occupies a very limited space. Therefore, we can clinch the importance of images.
We can observe that the images are not numbered, nor described or commented. But, as already mention, they are not enriched by many details. The only exception regards the first part in which geometric forms are presented and commented according to their properties.
If we focus on the organization, we can presume that the book was destinated to be used mostly for academic studies and also to be used as theory base for eventual fortifications of cities. The clear structure of text alludes to an attempt to make it more readable and, consequently, easier to be studied and to be understood. The large headings and the descriptions on the sides help the reader through the entire text.
