Il mostro torchino o Bellinda ed Azor ossia La Virtù premiata (The turquoise monster, or Bellinda and Azor or the rewarded virtue) is an anonymous text for puppets published in the collection of popular booklets “Raccolta teatrale” published by Fratelli Miglio. It is visibly inspired by the fairytale La Belle et la bête (Beauty and the Beast), made famous by Jeanne-Marie Leprince de Beaumont’s version (1756).

Isabella complains about being in the countryside to her husband Leandro. Her sister Bellinda downplays the situation. Petronio, their father, has been going through some financial difficulties but he announces that things are looking up and that they may be able to go back to the city. As he leaves, Isabella asks him to bring back clothes and jewels for her, and Bellinda only asks for a rose bush. After several misadventures, Petronio and his servant Gerolamo arrive in a nice place where a table is set, but no one is around it. They eat, drink, sleep, and find the horses ready for departure. As he walks through the garden, Petronio wants to get a rose bush for Bellinda, but thunder breaks out. The monster Azor, the owner of the place, tells Petronio that he is an ungrateful thief and that he will pay for it with his life, unless one of his daughters sacrifices herself to save him.

Petronio relates what happened to his daughters. Bellinda decides to follow him and to sacrifice herself to save him. They arrive at Azor's palace and eat. Azor asks Bellinda if she came here willingly. Her father does not want her to stay, but she does anyway. A fairy reassures them. The monster is ugly but kind: he wants Bellinda to keep him company. However, she sees in the mirror that, back home, her father is ill. With Azor’s permission, she leaves but promises to be back soon. Unfortunately, Isabella, jealous of her sister’s wealth, holds her up. Sad and disappointed, Azor hides. Bellinda finds him and tells him that she wants to marry him. The curse under which he was breaks, and, thanks to Bellinda’s love, he turns back into a handsome prince. He brings Petronio and Gerolamo to his gorgeous palace, and relegates Isabella and her husband to a tower.
