The beauty of nude is geometrical 1 /Cranach and Seurat

.

The most widely used motif throughout history may be a nude figure.
Why can we recognise by sight who painted the masterpieces of a nude?
Nudes by Seurat and Cranach can be easily distinguished.
Looking at a shape is looking it geometrically.
The circle-cross model should give us some clue.

Black diagonals indicate the center of the picture.
The red circle surrounding the lower belly and two largest blue circles pass through the center.
The largest blue circles and the second largest green circles form the basic structure.
The red circles are concentrated on the upper body and lower legs and
many of them are bundled together.
Three straight lines are made of lined units.

I deviced a new model made of arc model and scaled circles.

I have written that "Arc is atom of art."
The technique is allways deviced using circles that is the extension of the arcs.

This picture uses five circles that look different in size.
All arcs are part of a circle, so the curvatuor is the same.
The long loose arc means that the circle of the arc is large comparing to the nude.
The nude has a plump part and a thin part.
This is because each part is made of different sized circle.
The largest blue circles form the long thighs.
The second largest blue circles form the arms, upper right thigh and the hind parts of lower legs.

The red circle is most useful to make unique shape of the nude.
The size is one fifth of the body height.
Chained arcs of the same size is very effective; the left arm and right knee are made of four red arcs.

I made body-proportion-circles model of the standing nude in the center of Seurat's [Model].

 

Seurat [Model]  body-proprtioned circles model

The standing figure in the [Model] can be made of only three circles.
As the smallest circles are only used for the shoulders,
it can be said that it is almost made up of two kinds of circles.
The largest purple circles have larger ratio to the body than the largest circles in [Venus].
The red circle is half the body, creating a smart figure.

It is clear that the ratio of the circles determins the character of nude.
