Mario Nigro from Pistoia by birth, Livorno by adoption, joined the MAC in 1949 and began his research for a "total space", characterized by simultaneous networks. The abstract art of the canvas is punctuated with rhythm and precision by a deep geometric grid that overcomes the Euclidean two-dimensionalism, made possible by a skilful alternation of bright and brilliant colors, such as yellow and green, in contrast with midnight blue and black. of the lines present, of variable thickness. In these optical-perceptive grids one abstracts oneself into another dimension and, where geometric lines intertwine in an articulated plot, Nigro's research becomes not only artistic but also ethical and philosophical, a dynamic transposition on canvas of the transience of human life. The work was exhibited at the 1st Biennial of the progressive contemporary art museum of Livorno.
