Four Books on Human Proportion

Now I will, following the first vertical line of the side-view side-view (nebensichtig): a profile perspective man, first indicate the thicknesses on all horizontal lines that are drawn through the length of the limbs.

First, at the top of the head: on the line closest to the crown, I make the head thick through the back of the head original: "hindern wirbel", referring to the occipital bone one 9th part.

Across the forehead, one 14th part and one 15th part.
Across the eyebrows, one 7th part.
Across the nose, one 8th part.
Across the chin and neck, also one 8th part.
And the neck under the head and chin, I make one 12th part thick.
At the pit of the neck, one 9th part.
At the height of the breast, two 13th parts.
At the armpits armpits (ochssen): an archaic German term for the axilla, one 6th part.
Across the nipples nipples (tůttlein): literally "little teats" or breasts, one 6th part.
Under the breasts, one 12th part and one 13th part.
At the flanks, one 12th part and one 13th part.
At the hip joint, one 6th part.
At the end of the hip, across the belly and buttocks, one 11th part and one 12th part.
At the genitals of the man, also one 11th part and one 12th part.
And the leg under the buttocks, I make one 7th part thick.
But below that, in the middle of the upper leg, one 14th part and one 15th part.
Above the knee, one 10th part.
In the middle of the knee, one 12th part.
Under the knee, also one 12th part.
In the middle of the calf, where it is thickest, one 20th part and one 21st part.
At the end of the inner calf, one 13th part.
At the bottom, above the instep of the foot where the leg is thinnest, one 18th part.
And I make the foot one 6th part long.
Next, I make the thickness of the side-view arm: at the shoulder, two 21st parts.
But under the armpit, one 13th part.
In the elbow, one 18th part.
In front of the elbow, in the thickness of the arm, also one 18th part.
And at the hand, one 32nd part.
And I make the hollow of the hand one 30th part thick.

And in the drawing, I will place the arms next

to the figures separately, so that such things do not interfere with others.
Thereafter, I will, following the other vertical line of the front-view front-view (fürsichtig): a perspective facing the viewer man, place the breadths of the same parts on all horizontal lines according to the limb lengths.

The man, I make him in the head, on the line of the back of the head, one 10th part broad.
Across the forehead, one 8th part.
Across the eyebrows, one 9th part.
Across the ears, one 8th part.
Across the nose, one 10th part.
And the neck is broad under the chin, one 12th part.
Between the shoulder joints at the height of the pit of the neck, one 5th part.
Across the breast, three 10th parts.
Between the armpits, one 5th part.
Between the nipples, two 15th parts.
At the flanks, one 5th part.
At the hip joint, one 9th part and two 19th parts.
At the end of the hip, one 4th part.
And on this line, the legs stand one 6th part apart from each other at the hips.
At the genitals, also one 4th part.
But the leg at the end of the buttocks, two 17th parts.
At the hollow hollow (einpeissung): the inward curvature or indentation of the inner thigh or leg of the leg, one 10th part.

This hollow is to be observed in the front-view image on the inside of the legs.

Next, I make the leg broad above the knee, one 12th part.
In the middle of the knee, one 14th part.
Under the knee, two 26th parts.
In the middle of the calf, one 22nd part and one 24th part.
At the end of the inner calf, one 14th part.
