In the center of the town of Siena, Italy, lays the Palazzo Publico which was built between 1297 and 1310. Inside the Palazzo Publico is the Sala della Pace, the Hall of Peace, which houses an early piece of Italian secular arta fresco that illustrates the effect government has on the city, its people, and the countryside.' The painter, Ambrogio Lorenzetti, depicted the "Common Good" as a king, sitting tall and strong above a line of smaller-sized, everyday people who are slowly making their way towards the "Common Good." This picture represents the subordination of private interest to the common good.
