Mario Nigro was an Italian painter. He moved first to Arezzo and then to Livorno, where he highlighted his first artistic qualities albeit in compositions largely pervaded by a tired pictorial traditionalism. Nigro's work crosses over into the field of optical art and from the mid-sixties into "minimal" art, also showing connections with a discipline such as architecture, so much so that in jargon some of his productions from the fifties are called "skyscrapers" .
