[Who is Sharaku?] Ⅷ syntactic device can Identify who painted

Nine block copies of ”Sumo-e" by　Sharaku have been neglected.

They exist only as photographs because they are lost by the Great kanto Earthquake.

Besides some people think they are fakes.

As the digital images are available I try to identify them by the syntactic structure.

                               Sharaku  [Jinmaku]  sumou-e

In the circle-arc model the most slow curve( brown ) can be seen on the lower part.

To  see the pivots easier I made green circle-arc model.

                             Sharaku  [Jinmaku]  green circle-arc model

Then I made the three circles deeper green and thicker to see  four pivot points easier.

Next model is orange red circle-arc model

                  Sharaku  [Jinmaku]  orange red circle-arc model

On this model I noticed that the five different sized circles (purple, green , orange , red and red ocher) intersect at a point on the left.

Let me make models of another sumo-e[Raiden] to find the same device.

       Sharaku  [Raiden]                            

This is more ornamental.

The same circle is used to make the stripe pattern of the left person's kimono and the outline of the right person's kimono .

                           Sharaku  [Raiden]  blue circle-arc model

                          Sharaku  [Raiden]  a pivot with four circles

The four different circles (purple,green,orange and red brown) intersect at a point ( large black cross).

And the green circle has three pivots.

Here is  a whole body portrait by Sharaku which has a typical syntactic devices.

                    Sharaku  [Yamasita Kinsaku] detail  circle-arc model

There are three devices which can be found in the sumo-e.

a) The largest brown circle intersects at the point(blue cross)bwith the three smaller circles(pink,green and orange red).

b)The largest brown circles and pink circles make many pivots (Yellow crosses and light blue crosses).

c)The pink circle which I made brighter has six pivots.

The pivot device is  also used for [Osiokuri-hato-tusen-no-zu (Namiura first version)] by Sori(Hokusai), about which I wrote previous time.

    Sori( Hokusai)  [Namiura first version]

The four circles (yellow, green, red and light blue) intersect at the point(pivot) on the upper left.
This is the same technique seen in the two sumo-e.

This sumo-e series turned out to be very important experimental works to establish Sori's mature style.

 I assert that Hokusai under the name of Sharaku executed one hundred sixty works more or less.
