The text outlines a series of drawing lessons, divided into three main parts: drawing general body shapes, drawing the head, and drawing the entire body or academies from nature. The first part is further divided into five chapters, covering rectangular objects, circular shapes, combination shapes, interiors, and landscapes. The fundamental aspects of linear perspective are emphasized as part of these lessons.
ORDER OF MATERIALS
We have divided this series of lessons into three parts, namely:
1. Drawing from nature the bodies in general, square and round, or rectangular and spherical.
2. Drawing from the statue or from nature, the Head.
3. Drawing from nature, the entirety of the body or the Academies.
FIRST PART
The first part is divided into five chapters.
I. Drawing from nature of boxes and other rectangular-shaped objects.
The basic and fundamental notions of Linear Perspective are deduced from the results obtained in this first chapter.
II. Drawing from nature and in perspective, the circles and objects of circular and spherical shape.
III. Drawing from nature, objects that combine rectangular and circular or spherical shapes.
There is not a body in nature whose forms cannot present any other combination than those dealt with in this chapter.
IV. Drawing from nature, the interiors.
V. Drawing from nature, the landscape.
It is important to note that it is in this first part that the entire method of Drawing from nature is properly found.
