Seurat's method to compose "A Sunday Afternoon on the Island of La Grande Jadde" in Barnes Foundation 3/ reconstruction with the new units

Sometime Seurat became conscious of using the method of composition.
This time, I devised a new structural model.
One can see the same bend in the curve.
Curves with the same bend can be regarded as arcs.
If we consider the arc as the smallest unit, we naturally come up with the idea of ​​using a circle, which is an extension of it, for designing.
The unit is made of a circle and its vertical and horizontal diameter,
In addition, the square surrounding the unit will be added to call it ‘the framed circular cross unit’.
A square is easier to adjust the balance effect than a circle.

Though the method could be invented independently,
it is possible that the method to make the basic structure with the largest circle was known.Since Hokusai's "Tomegane" makes the basic structure with the curved circle of the bone of the umbrella,The technique seems to be logically guided.

As some figures are not outlined clearly due to the pointilistic finish,
I try to reconstruct thecomposition with framed circle-cross unit.
