A boccaperta, as stated in the work itself, is an Italian screenplay written in 1970 by Carmelo Bene, even though most consider it a novel. In most of Bene's works is hard to recognize a sole genre: he himself defines his own art as "degenerate". It was published in 1976 in bundle with S.A.D.E. and Ritratto di signora del cavalier Masoch per intercessione della beata Maria Goretti.
