Ambrogio Lorenzetti
The frescoes on the walls of the Hall of the Peace (Sala della Pace) in the Palazzo Pubblico of Siena are one of the masterworks of early renaissance secular painting. The "nine" was the oligarchal assembly of guild and monetary interests that governed the republic. Three walls are painted with frescoes consisting of a large assembly of allegorical figures of virtues in the Allegory of Good Government. In the other two facing panels, Ambrogio weaves panoramic visions of Effects of Good Government on Town and Country, and Allegory of Bad Government and its Effects on Town and Country.
