Montesano was born in Turin in 1949 and was educated in Turin in the Salesian Seminary of Valdocco. He did not follow the ecclesiastical vocation because he had a strong artistic and intellectual predisposition that led him in the seventies first in Bologna and then in Paris. The initiation of Montesano's painting took place a long time before, while he was still a seminarian at Valdocco. In the early seventies his first works are reproductions of Madonnas and of those sacred images, memories distributed to the faithful in the sanctuaries and during the spiritual exercises. Montesano magnifies them and revisits them in a postmodern key, referring to the beautiful tradition of popular painting but also covering them with conceptual and theoretical meanings. Next to these images there are also very sweet images of children, seductive female portraits, vast landscapes of romantic taste, urban views of film genre, which Montesano paints with his unmistakable neorealist style, even post-realist. In addition to being a well-known painter, Montesano is an impassioned theatrical director. His ''Florian Company'', based in Pescara, has presented shows in Paris, Hungary and throughout Italy.
