 Among the episodes of the novel there was the failed anarchist insurrection of 1874 in Bologna, which brought the young Andrea Costa to jail.The insurrection was meant to start at the Anarchist meeting at Prati di Caprara and precisely at Pontelungo’s bridge, between the rione Santa Viola and Borgo Panigale.In April 1906 Prati di Caprara was the site of the second Buffalo Bill’s Italian tour, as documented by the photographs of Indians riding outside the exhibition tent.
