ARRANGEMENT OF THE FIRST BOOK.

A hierarchical branching diagram organizes the contents of the first book. It uses brackets to categorize topics from general to specific, ending with corresponding page or proposition numbers on the right margin.

Fortification is of two types, namely:

1. Geometric, which contains:

ARRANGEMENT OF THE SECOND BOOK.

A second hierarchical branching diagram organizing the contents of the second book, focusing on the theory and practice of surfaces, profiles, and ground plans.

The Surfaces are considered:

In theory:
- 1. The Profile, in which one observes:
  - The invention:
    - Of Parapets protective walls or elevations atop a rampart to shield soldiers:
      - Alone, where one will see:
        
        Their construction, in Proposition 1.
        
        The calculation of their contents. Proposition 2.
      - With various Banquettes steps or ledges behind a parapet where soldiers stand to fire over the top, in Proposition 3.
    - Of Ramparts for the bastions:
      - Solid or filled with earth. Proposition 4.
      - Hollow. Proposition 5.
  - The composition, where it treats:
    - The invention of the parapet for the Covered Way a protected path on the outer edge of the ditch. Proposition 6.
    - The ditch, the paths, and the Berm Original: "lisiere." A narrow level space between the foot of the rampart and the edge of the ditch.. Proposition 7.
- 1. The Ichnography the ground-level floor plan:
  - Of the Rampart and figures:
    - Regular:
      - Of small works:
        
        Without defense, namely the calculation. Proposition 8.
        
        Of Redoubts, the delineation of their ground plan. Proposition 9.
        
        With defense:
        
        Of Star Forts:
        
        The calculation. Proposition 10.
        
        The delineation. Proposition 11.
        
        Of Forts with half-bastions:
        
        The calculation. Proposition 12.
        
        The delineation. Proposition 13.
      - Of large works:
        
        Square and half-square types Original: "Quadrantaux.", which are:
        
        Calculated. Proposition 14.
        
        Traced. Proposition 15.
        
        Three-quarter and Royal types Original: "Dodrantaux & Royaux." "Royal" bastions were the largest standard size in 17th-century systems., also:
        
        Calculated. Proposition 16.
        
        Traced. Proposition 17.
    - Irregular, concerning the ground plan of irregular figures. Proposition 18.
  - Of the ditch:
    - Of small works:
      - Without defense, namely Redoubts. Proposition 19.
      - With the defense of Star Forts. Proposition 20.
    - Of large works, such as:
      - Forts with half-bastions. Proposition 21.
      - Square and half-square types. Proposition 22.
      - Three-quarter and Royal types. Proposition 23.
In practice, where the manner of seeing if the ramparts are well-made is shown. Proposition 24.
