Fiesole enters the Decameron as the place associated with a rector whose attempted seduction ends in public exposure. The town is not described topographically; its name identifies the cleric and frames a story about desire, failed deception, and the intervention of the local church hierarchy.

Role in the Story

The episode concerns the rector of Fiesole, who loves a widow but is not loved in return. Seeking to lie with her, he instead lies with one of her serving-women. The widow’s brothers arrange for the bishop to discover him in the act, turning his concealed intention into an ecclesiastical embarrassment.

The Town and Its Institutional Association

Fiesole is attached to the rector’s office rather than developed as a physical setting. The story gives no streets, landscape, or civic customs of the town, and does not establish that the encounter itself takes place there. What it does make explicit is a chain of authority: the rector is exposed through the widow’s brothers, and the bishop is brought in to find him.

Narrative Significance

The episode uses Fiesole’s clerical association to sharpen the contrast between religious office and sexual conduct. The rector’s desire is frustrated in its intended form, but his conduct is not thereby made innocent: he ends up with the serving-woman and is discovered. Fiesole consequently serves as the identifying frame for a brief anticlerical comedy, not as a separately depicted landscape.
