In the section there is the allegory of Pisa, a work by Giorgio Vasari: the town is in the background, while in the foreground the lady, symbol of the city, holds a horn of abundance that flourishes thanks to Duke Cosimo I de' Medici (referring to his intervention of drainage in the area) and receives from him the laws. The view below, painted by Giovanni Stradano, shows Siena. Photo: Simone Lampredi
