S. Yatnov was born in 1958 in Dzerzhinsk (former Gorky region and now the Nizhny Novgorod region) where he graduated from an arts school for children. After graduating with a Master's degree from the Gorky University of Construction in 1981 he moved to Sochi to work as an architect. S. Yatnov took part in several exhibitions of young painters of the southern regions of Russia there and soon he made his choice between the professions of an architect and of a painter. Sergey became an independent artist and fully devoted himself to painting in 1987.
In 1991 he began to work in Prague, where his career as a European artist of Russian origin started. He began exhibiting his paintings in art galleries of Prague in 1994. Here he found his favourite themes among which are the roofs of Prague, the scenery of the night city with its mysterious old streets and secluded corners. The artist began to cooperate with the art gallery "Russian Age" in Nizhny Novgorod in 2002. New themes and images consonant with Russian traditions came to his paintings -angels, nude figures. Now Yatnov works both in Russia and in the Czech Republic. Each of these countries gives him new impressions. Sergey Yatnov joined the "International Arts Fund" in 1999" and "Creative Union of Russian artists" in 2004.
Two tendencies can always be traced in his paintings —European freedom and formalism and realism of Russian figure compositions.
The artist himself says that the desire to paint comes from inside as a wish to solve the main problem formulated as follows:
"To understand the very essence of the beauty, to find elements which form and to create something that has not existed before.
Everything in a painting, all its elements - its texture, line, glazing, spot, colour, composition - belong to one of the opposites - either to plane or to volume.
Their interaction forms what I have been searching for all my life, the beauty."
