Niccolò Tornioli (Siena, 1598 – Rome, 1651), made a name for himself in Rome, where he achieved considerable success, thanks to the great consideration of prominent personalities such as Francesco Borromini and Virgilio Spada. The reason must be sought in his extraordinary skills in all techniques, oil on canvas and on wood, fresco, painting on marble, but the authentic charm of his art lies in the originality and in the mystery that surrounds the subjects of his works, taken from literary and biblical sources little used by colleagues, and therefore rare in painting, and his style that oscillates between suspended and chiaroscuro atmospheres by Caravaggio and his followers and the opulence of the drapery, the brilliance of the colors of the Baroque matrix. He was also a tireless designer and an imaginative designer of ephemeral apparatuses. They retrace, in ten chapters, the stages of his career and investigates the character of a man who reveals himself at the same time naive and arrogant, shy and determined, creative and conventional, contrasts that will lead him to collect successes in the face of real fiascos that will weigh heavily on the critical luck.
