His artistic inclinations and talent for drawing were evident in his youth, however his father compelled him to study commerce; he went to boarding school in Bern and later worked in Milan for a brief period.
He enrolled the following year at the Rossetti Valentini School of Fine Arts[1] in Santa Maria Maggiore, where he took courses in painting, drawing and ornamentation taught by Enrico Cavalli.
Lorenzo Peretti Junior then moved away from Divisionism and set out along a solitary pathway, a personal synthesis of research, a scientific approach and mathematical rules with the spontaneity of the gesture, the immediacy of the sign and the emotional and sensory values inherited from Cavalli: a rejection which definitively excluded him from the avant-garde movements and the attention of contemporary criticism.
An increasingly solitary and eccentric figure, often mystified by the diffidence of his fellow townspeople (who believed he knew the secrets of the archaic sorcery of the Valley) and the superficiality of the criticism of his work, Lorenzo Peretti Junior spent the last decades of his life living in seclusion at Toceno, devoting himself mostly to studying and critiquing art.
An analytical, in-depth reassessment of his role in the art of Valle Vigezzo and Italy generally at the turn of the 20th century would not be carried out until the 1990s, with the research of the Piedmontese critic Dario Gnemmi (1957-2005), in particular the volumes Retour à la ferme (Return to the farm) (1993) and the posthumous Vigezzini di Francia.
