The “0.10 Exhibition” (full name: “Last Futurist Exhibition of 0.10 (zero-ten) Paintings”) was an exhibition of Suprematist and Futurist painting organised by fourteen artists, including Kasimir Malevich, Jean Pougny and Ivan Klioune. It was held in the Dobychina art gallery in St Petersburg from 19 December 1915 to 17 January 1916. This exhibition introduced a new school of art known as Suprematism. It should be noted, however, that none of the paintings in the catalogue was labelled “Suprematist”. Malevich explained this as follows: “By naming some of these paintings, I did not want to indicate the form that should be sought in them, but rather to indicate that real forms served as a foundation for the shapeless masses that make up a painting, without any relation to the forms that exist in nature”. Malevich had placed his Quadrangle (black square on white background) in the corner formed by the walls, underlining the exceptional status of this work. He later went so far as to consider the entire wall as a Suprematist painting, and varied the direction in which his works were hung according to the group of paintings on the wall. None of the artists living in St Petersburg escaped the shock provoked by this exhibition. It heralded the role of abstraction in the revolutionary enterprise.
