Angle of light - what is it?

[I-V]

Reading the notes outstanding artist Eugene Rastorgueva (1920 - 2009), I was faced with the fact that do not fully understand the meaning of some of his statements. Although intuitively feel that he is right, and get to the point it would be very helpful. I hope for your assistance in this matter. Thank you.

"Perspective of the world - one of the basic laws (painting - drawing). Cezanne Thoughts of a cylinder, sphere, cone - are probably the same for him.
Without the angle of light in the drawing and painting, or all watermelon-volume, or all of the iron-flat.
It's two sides of the same anti-artistic approach to nature. "

"Perspective of the world - the closest he came to the decision of Cezanne."

"Perspective of the world - destroy the materiality of color and gives a plan."

And another very interesting idea:

"I've noticed that even the strong artists are pretty good write clear bottle or box, because it is a problem: the light coming, (that would be a mysterious celestial light) on the artist in these things or places in nature - he combined.

But when they meet with an opaque form of: a tree, hill, house, or objects, they are lost, because the object is displayed, followed by the darkness begins. This problem is completely solved by the ancients, and then the Impressionists and Post-Impressionists. We have it completely solved P.Kuznetsov. "

As for bottles and windows, which are surprisingly well written beginners - I totally agree, he is seen many times. But the explanation of this fact in P. did not quite understand, but his thoughts are important and valid, as it seems. And what did he mean, speaking of the merit P.Kuznetsov? Waiting for clarification from you, dear forum <! - ~ 1 ~ ->
