The text discusses techniques for drawing arms in foreshortened perspective, specifically focusing on proportions and measurements. Instructions are provided for maintaining accuracy by following specific artistic rules, such as using perpendicular and diagonal lines for reference. The explanation is given in multiple languages including Italian, French, Dutch, and German.
THE SECOND PART
SECOND PROBLEM OF THE SHORTENED ARM
This figure of the arm viewed from inside, slightly bent at the elbow, as shown here, is expressly made at the beginning discussing proportions and measurements to obtain certainty of the shortening, and it should serve the same rule we have written above to do perpendicularly to the diagonal marked to the extremities of that. And to make the shadows [...]
SECOND PROBLEM OF SHORTENED ARMS
This figure of this arm seen from the inside, slightly bent at the elbow, as represented here, is purposely for the third figure along with the other, which starts with discussing proportions & measures. And to obtain the certainty of shortening, follow the same rule written above, drawing perpendiculars to the lines [...]
SECOND PROBLEM
or explanation of the shortening of the arms.
This figure of the arms, intended to be seen, slightly bent at the elbow, displayed as previously explained, and precisely how the third figure [...]
EXPLANATION OF THE SHORTENING OF THE ARMS.
This figure of the arm seen from within, slightly bent at the elbow, as presented here, and precisely made for the third figure from the side as portrayed, starts discussing the measurements of forms. To ensure the shortening as fully as possible, one must use the same order [...]
Translation Notes:
- "racortamento"/"raccourcissement" - shortening or foreshortening in artistic terms to describe how the arm is strategically depicted.
