The text emphasizes the importance of learning Geometry and Perspective for young artists, as they are foundational for painting. Geometry is highlighted as essential not only for art but also for architecture and sculpture, while perspective is crucial for accurately representing objects without relying on tools like rulers or compasses. The text suggests beginning the study of these subjects in youth for more effective learning.
Method for Learning
It is of utmost importance for young people to properly start painting and to make great strides by not abandoning these first two exercises until they have acquired great skill.
On the Study of Geometry and Perspective.
Alphonse Dufrenoi and his Commentator believe that young people should begin by learning Geometry, as it is the foundation of Perspective, without which nothing can be done in painting. Mr. de Piles adds that Geometry is also very useful for Architecture and everything that depends on it; finally, it is especially necessary for Sculptors.
Since Perspective assumes Geometry, it is natural to place its study here: and to focus on it even more strongly because the Painter derives a service from it that is impossible to do without, whatever project they may undertake.

(b) I do not believe that one needs anything other than natural Geometry; this means one must have a mind capable of combining ideas clearly. Therefore, it should not be required as essential to Art to learn the geometry of lines and surfaces, but only suggested as something that could be useful. What is necessary to know about it for properly learning perspective does not extend very far, and is reduced to a few practices taught in basic geometry. Le Clerc, in twelve.
(c) It is necessary to study Perspective in youth, because it cannot be learned or at least only with difficulty at an older age. I mean; such that it is suitable for a Painter to do it; because it is not the same for an Artist in this regard as it is for a Mathematician, who having understood the truth of the propositions, and one or several methods, possesses the science of perspective. A Painter must practice it, meaning, through practice, they have all effects present in mind, allowing them to define all the objects they intend to represent and to put them in perspective with enough accuracy, without rule or compass; so that they are not obliged to decompose a sketch, where all the figures
