The geometrical structure in Matisse's 'The Dance' in Barnes Foundation / Ornamental paintings and pictures are made using the same technique

We can easily find a masterpiece by looking at Matisse's art book,
The time taken for the aesthetic judgment of a picture is almost instantaneous.

Though the number of artworks becomes almost infinite when we recognize that digital images are also works,
the masterpieces can be easily taken out of these by the taste judgment.

The picture below is “The Dance” by Matisse from the Barns Collection, which is a decorative painting.

 

As we know that this was made as mural, I can make a circular cross model with more confidence.

 

     Matisse [Dance] Barnes Foundation / circle-cross model
The blue circle that forms the arch is used as the main harmonic circle.
Seurat used the same technique for [Cancan].
(The color has been changed from blue-purple to blue-green for explanation sake.)

When the circle  (blue purple) that makes the back of the left nude is shifted horizontally to the right, it overlaps the circle that makes the middle nude shin.
The left nude waist and right front lower leg units overlap on the vertical line.
The second largest red circle unit (bright pink) also contribute to balance.

 
The upper left thigh of the nude on the left, the back of the left foot of the middle nude and the lower part of the right thigh are lined up on the horizon.


Furthermore, the leftmost unit and the unit that creates the right calf are lined up on the vertical line.
Two third largest units (orange) are placed on the horizon

As I know better about Matisse's model making now, try to make a model for mural [Dance 2].

It is no coincidence that I have taken up [Dance 2]and [Pink Nude] for analysis.

The masterpiece is something I want to have a copy at hand to enjoy seeing repeatedly.
Consequently I started thinking  why it looks so interesting. 
It is scientific practice to create and explain structural models.
