The section on the right side of the fresco, where the Montemassi Castle is situated, was repainted in the late-1400s.
The sky was also touched up after the frescos were completed. Both the leader of the troops is in the center, and the encampment on the left, are in good condition, even though they have lost their rich, original decorative elements. Both paintings by Martini, which face each other in the Sala Maggiore, counter civic glories against the religious and political glories of the city.
Martini painted a cycle of narrative fresco that retells the conquests of the city of Siena in the surrounding countryside: castles in the Maremma and Amiata that they conquered in the 1300s and the 1400s. In the Mappamondo room in Siena’s Palazzo Pubblico, Martini’s artwork depicting the mercenary commandant is considered one of the most illustrious works of the era, after Leonardo’s Monalisa and Raphael’s many Madonnas.
