In Wikipedia, little bits of information are collected about this artist. In principle, he is completely unknown to us. And primarily because of the fact that he left the USSR and stayed to live in the West. He worked a lot, he has a lot of paintings, which are now estimated at decent money at Russian Sotheby's auctions. But at the same time he exhibited many times in the Tretyakov Gallery, but this was before the revolution. And in pre-revolutionary Russia, he was very popular.
Before us are two canvases on a seemingly one and the same theme - “Landscape with a Rainbow”. But there is something the same in them. The upper canvas was created in 1915 and therefore it blows from it with some kind of romanticism, some even mercantile style of village life. You can see the park with blooming flower beds and "walls" of climbing plants. And in the clearing, cows roam freely.
Rainy weather is only a joy to them, because a stuffy summer sometimes exhausts not only people, but also cattle. And a girl hid in the arch. But the storm had already passed, and the sun came out from behind the clouds, and therefore a rainbow formed against a dark background.
On the second canvas, which was written in 1919, almost everything is the same. The same thunderstorm, but no animals. But now there are now two women with a child who hid from a blind summer rain under the crown of trees. The color scheme has changed.
The first canvas was a bit gloomy, despite the colorful decoration of the flowerbed; the second is bright and radiant. The landscape has changed - it has become more relaxed, many trees. There was a place for birch and shrubs. And the rainbow here is not against the background of dark clouds, but against the background of well-lit clouds.
By the way, the style of the picture has changed a bit. On the first canvas everything was drawn in more detail, but in the second it was somehow more sweeping and not dwelling on the details.
