In Dioneo’s fourth tale (IV, 10), the Trusted Maid serves Mazzeo’s Wife faithfully and helps her conduct her affair with Ruggieri d’Aieroli. She helps her mistress dispose of his body when they think he’s suddenly died and convinces the judge to drop the charges against him. She demonstrates the intersection of concerns about class and female sexuality; while noble Andreuola was praised for not having sex with the magistrate in an earlier tale, part of the humor of Dioneo’s tale is the way the maid readily acquiesces to his demands for sex in exchange for Ruggieri’s acquittal.
