Guevara-Moreño was born in Valencia, Venezuela in 1926. He lived in Paris from 1950 until 1955 and participated in the Dissidents group. He became a member of MADI and was awarded several important prizes. He was a three time first place winner in the Nacional de Pintura, Dibujo y Grabado in Venezuela. Guevara created optical effects in his coplanals, thereby making diagonal lines appear to be zig-zags. Vasarely later used the same technique on a monumental scale.
MADI is a great artistic adventure, and perhaps, the only existing movement which can justify half a century of existence. MADI is more than an avant-garde movement; it has an underlying wave with several and differing offspring. It is the slow-paced growth of a tectonic plate in the history of art. Indeed, since art and environment are perveived as the fusion of two cultural phenomena, the progression and expression of both of these blend in everyday life.
