Parmigianino frescoed the smallest hall for Paola Gonzaga in 1524 with scenes taken from Ovid's Fable which narrates the story of "Diana and Actaeon". (Metamorphosis of Ovid, book III, vv. 138-253).

The fable interweaves with the lives of the commissioners, investing them with symbology and alluding to esoteric themes.

Amongst the figures, portraits of Paola Gonzaga and her two children appear.
The hall has been restored by the Works at the Pietre Dure of Florence under the direction of the Service for Historical, Artistic and Demo-ethno-anthropological Heritageof Parma and Piacenza, and was handed back to the public in May 1998.
