"Russia's modern abstraction of secondary importance to define"

[Pavel]

I heard that Kandinsky was a mathematician and his abstraction is mathematically constructed compositions. He is a German artist and he has clearly read the influence of German expressionism. If desired, traces of abstraction can be found in the manuscript illustrations of stained glass, etc.
The problem is that now all the development of abstraction have been exhausted. I mean the picturesque route. Not enough to make an abstraction, must be original. It only seems simple.
