Marianna graduated in Architecture and worked for some years for the Chicago Driehaus Prize winner, P.C.Bontempi. At the same time she practiced photography, with the support of Vasco Ascolini (Chevalier de l'Ordre des Arts et des Lettres of France). Her first catalogue was published by the editor and art collector Franco Maria Ricci. Marianna travelled the world studying art until she moved to Florence to work in various botteghe, learning the ancient techniques alongside expert maestri. She learned the techniques of painting (including fresco), engraving and sculpture, and began to devote herself chiefly to the latter. She was awarded a Fondazione Alimondo Ciampi fellowship, a Fondazione il Bisonte fellowship, and recently won the prestigious Fiorino d'Oro prize awarded by the Florence City Council. Her sculptures can be found in some of the most important churches of Florence, and in private and public collections.
