Universal Flowering (Mirovoi rastsvet) is the name given by Pavel Filonov to his system of analytical art . The system arose from cubo-futurist experiments and works that he undertook from 1913-1915. It is characterized by very dense, minutely facetted, and relatively flat surfaces. The images have both Cubism's multiple vantage points and Futurism's representation of a figure over time. A number of the paintings, while having a given orientation, are painted as though they could be oriented in a variety of ways. Filonov's philosophy was originally formalized in written form in 1915, which was revised and published as The Declaration of Universal Flowering in 1923 when Filonov was a professor at the (then) Petrograd Academy of Arts. Filonov's main theoretical work The Ideology of Analytical Art (Ideologia analiticheskogo iskusstva) was published in 1930.
