The text discusses the proportional characteristics of the human head, noting that immovable parts have a proportional relationship regardless of age. It goes on to describe how lines dividing the height into eight parts can reveal these proportions. The observations are aimed at guiding the reader to understand and identify these proportions in artistic prints.
Concerning the recognition of the characteristics in the heads of men and women, my knowledge suggests nothing of significance has come to light. I would like to add my observations on the characteristics and features of male and female heads. These immovable parts have a proportional relationship to each other, even if the individuals vary in age. The reader is encouraged to proceed to the examination of the prints where these details can be adequately noticed.
Firstly, in the case of measuring by eight heads:
The lines that divide the height into eight equal parts not only touch various significant parts, as you can see, but the entire height of the image equals the length between the extremities of the fingers of that same image when both arms are extended horizontally. It is positioned precisely in the center of a square. The feet are on the bottom line, the head touches the upper line, and the longest left finger reaches the extreme side.
Moreover, something worthwhile can be contributed to the public regarding this subject, as well as my observations on human characteristics. There is evidence that the immovable parts in each head have a proportional relationship, regardless of differing ages. The reader will kindly move on to the consideration of the prints and notice the following specifics, which couldn't find a suitable place in the Plates.
Firstly, regarding the measurement by eight heads:
The lines that divide the height into eight equal parts touch and intersect several main parts, as this is immediately noticeable. The total height of the figure is parallel to the length between the extremities of the fingers. When both arms are horizontally extended, it is precisely centered in the middle of an equilateral square. It is positioned with the feet on the lowest line and touches the highest line with the head. The longest finger of the left hand extends to one extreme side.
Translation Notes:
"Horisontaal" in modern context is translated as "horizontally." The anatomical concepts described involve dividing the human figure into standardized proportion units for the purpose of studying symmetry and balance in art.
