Text in Italian.Leonardo Da Vinci had significant relationships, so far mainly neglected, with the town of Bacchereto (near Prato in Tuscany) and its ceramic kilns, thanks to the family possessions of his paternal grandmother Lucia, and then to his father Ser Piero. The volume reconstructs Leonardo's surprising studies and his multiple experiences in shaping clay.Contributions by Maria Chiara Bettini, Giovanni Roncaglia, and Agnese Sabato.
