Kuzma Petrov-Vodkin was born in Khvalynsk (Saratov Oblast) into the family of a local shoemaker. His first exposure to art was in his early childhood, when he took some lessons from a couple of icon painters and a signmaker. Still, Petrov-Vodkin didn't quite see himself in art at that time; after graduating from middle school, he took a summer job at a small shipyard with plans to get into railroad college in Samara. After failing his exam, he turned to "Art Classes of Fedor Burov" in 1896
In April 1895, Burov died and for some time Petrov-Vodkin took different painting jobs in the vicinity of Saratov. By chance, his mother's employer invited a well-known architect, R. Meltzer. Petrov-Vodkin was introduced to the guest and impressed him enough to get an invitation to study art at Saint Petersburg. The education was financed by a charitable subscription among local merchants. He also met at this time Borisov-Musatov, an important painter resident in Saratov, who encouraged Petrov-Vodkin to continue his studies.Wikipedia
"At the time when the Russian Empire was suspended between two revolutions and was undergoing a radical social and political changes, emerging avant-garde artists were working on manifesting new modes of artistic expression. They either rejected classical art altogether in favor of completely innovative approach, or stylized art of different epochs and cultures endowing it with new meanings. Kuzma Petrov-Vodkin synthesized both approaches when he painted Bathing of the Red Horse in 1912.
That being said, it should be noted that the powerful blood-red stallion was a product of the artist’s own world. Or could it have been the world of his student? It is believed that Petrov-Vodkin was inspired by a sketch “Red Horses” by his pupil, painter Sergey Kalmykov, who would become a model for the boy. The choice of the setting, circular composition and symbolism pervading the work also brings to mind Frantisek Kupka’s L’Eau.
A simple plot, rounded lines, dominating intense red and clear bright colors in the background, and finally not quite mythological but rather a symbolic horse – made this work an icon of the Russian avant-garde. Consequently, this image would become not simply iconic but even prophetic after the Bolsheviks took over the Imperial government and transformed the Russian Empire into the USSR. The red flag would serve as a symbol of the new country for the following seventy years. Petrov-Vodkin returned to the subject once again in 1925 with a painting titled Fantasia, (featured in this article) where the boy on horseback is now flying over the mountains."(galleryintell.com)
