The Enciclopedia Universal Ilustrada Europeo-Americana describes Manuel Sáez as among the most important painters of the turn of the 21st century owing to his simultaneously sensual and psychological approach to the world of objects, landscapes, figures and portraits [REF].
As a resident fellow of the Spanish Fine Arts Academy in Rome in 1990, Sáez elaborated a series of portraits called Biografia no autorizada ("Unauthorized Biography").
