Niccolò Machiavelli,
History of Florence and Of the Affairs Of Italy Book II…
“ These buildings were completed in a few years; nor did our city ever enjoy a greater state of prosperity than in those times: filled with men of great wealth and reputation; possessing within her walls 30,000 men capable of bearing arms, and in the country 70,000, while the whole of Tuscany, either as subjects or friends, owed obedience to Florence. And although there might be some indignation and jealousy between the nobility and the people, they did not produce any evil effect, but all lived together in unity and peace. ”
