Based on a historical bishop who was a near contemporary of Giovanni Boccaccio, Antonio d’Orso appears in Lauretta’s sixth tale (VI, 3), where he hosts Catalan nobleman and scoundrel Dego della Ratta. He ignores Dego’s forced affair with his relative and is punished for making a sexist and demeaning comment to Nonna de’ Pulci when she offers a scathing retort implicating the bishop’s relative for her affair.
