ARMAN (1928-2005). The cogs. Accumulation of cogs under Plexiglas numbered lower left 170/900, Artcurial edition and signed lower right (small chip). Height : 46 cm - Width : 46 cm Note: Franco-American artist and founder of the Nouveau Réalisme movement with art critic Pierre Restnay and artists such as Yves Klein, François Dufrêne, Raymond Hains, Martial Raysse, Daniel Spoerri, Jean Tinguely and Jacques Villeglé, later joined by César, Mimmo Rotella, Niki de Saint Phalle, Gerard Deschamps and, in 1963, Christo. He made a name for himself with his accumulations, in which he assembled large numbers of identical or related objects from everyday life. Among these series, accumulations of cogs, mechanisms, springs and metal parts play a key role. By imprisoning these cogs, Arman literally freezes time and mechanics, transforming utilitarian elements into sculptural landscapes where repetition creates rhythm, density and visual tension, while prompting questions about consumer society. In 1976, he created Divisionis Mechanica Fossilia, an accumulation of cogs and metal parts set in concrete, installed at the University of Burgundy in Dijon.
