ABSTRACT
Future cities will concentrate more people and activities, more institutions and investment, more risks and opportunities. They will be more complex and diversied than current ones. The eects of their good or bad government will be increasingly inuential. All this seems to justify a dramatic update of the allegories on the eects of good and bad government in the city and in the country, depicted in the frescoes of Ambrogio Lorenzetti at the beginning of the 14th century.
