A journey following the footsteps of Costantino Nivola (1911-1988) to compose a mosaic where art and life merge. Not a critical compendium or a didactic summary, but a personal emotional journey, carried along by the voices of family, colleagues, and Nivola himself, and interwoven with never-before-seen photos. It tells the story of a mason who became an artistic genius. From his native village of Orani, in Sardinia, to New York: an ideal bridge of stone, marble, and sand that bears the indelible mark of his peasant island roots, where the ancestral call of the past revives, inhabits, and dialogues with the technological present of the metropolis.
