The text demonstrates how two figures can be used to show the front and back view of a body. It explains foreshortening of the arms and the use of shadows to create a sense of depth, marked as A and B. The text suggests that these methods adhere to standard drawing techniques to achieve the desired perspective.
THE SECOND PART
PROBLEM V
Demonstration of Two Figures: One in Front, the Other Behind.
These two figures are presented to demonstrate that a figure seen from the front can be reversed to show the back, and vice versa. This is evident by examining these figures. The arms are foreshortened as marked A. B., demonstrating shading from their own shadows as described above, showing how to achieve this with ordinary methods.
Demonstration of Two Figures, One Viewed from the Front and the Other from the Back.
These two figures are proposed to demonstrate that from a figure seen from the front, one can construct the back, or vice versa (as shown by these figures). The arms are foreshortened, marked A B, by their shadows as previously explained, illustrating how to attain the foreshortening using ordinary methods.
Representation of Two Figures, One Seen from the Front, the Other from the Back.
These two figures are placed here to show that one can place the top image opposite or make from behind the frontal view, clearly indicated by these figures. The foreshortening of the arms, marked with A. B., and their shadows are shown as described above, to achieve this one must use the ordinary method.
Arrangement of Two Figures, One Seen from the Front, the Other from Behind.
These two images are presented here for instruction, showing how the front can also be made from behind (one against the other), or make from behind what appears from the front, as indicated by these images. The foreshortening of the arms indicated with A. B., using their own shadows, as I have constructed here, shows how to obtain this foreshortening, one must use this ordinary method.
