The provided text draws a comparison between human proportions and those of Ionic columns, stating both are equally beautiful and dignified. It offers a method to depict a man's posture, using a vertical line split into nine sections to guide the proportional measurements. The instructions include details on aligning body parts with calculated measurements to achieve symmetry and balance, reflecting accuracy and attention in stature, similar in elegance to classic Ionic columns.
The Second Part
V. Problem
Because there is a conformity between the proportions of columns and those of men (as stated), we will represent a man of dignified and conversational posture, comparing him with the noble Ionic column, which is much more excellent than the Doric, and equally beautiful. Drawing a straight line from the top of the head (A) down to the bed of the foot (K), this divides into nine equal parts. A is the arch; E corresponds to the navel sphere; B and C shows measurements for various parts of the body. F indicates the thickness of the thigh; G denotes the knee joint and finally ends at H, where it connects to the calf of the leg, marked by I and H.
Beginning with the line marked nK, which is the second ratio between two heights, one places a compass at C that passes over the circumference of the chest at (E) and through (B), cutting through (I, M), which determines the width of the shoulders. I make the width of the shoulders, 0.6 a measure from the breast, shown (N) & with the Mod. from Modavalica, 2 Modules per size, from P, which is above the knee by two and a half modules, and ending at Q, which is minute of the leg appointed by the Module Khan. Finally, R, which denotes the complete height, Ending our proposal and description with what is directed as our enterprise.
