Silver mining
During the Renaissance, money and art went hand in hand. Artists depended entirely on patrons while the patrons needed money to foster artistic talent. Wealth was brought to Italy in the 14th, 15th, and 16th centuries by expanding trade into Asia and Europe. Silver mining in Tyrol increased the flow of money. Luxuries from the Muslim world, brought home during the Crusades, increased the prosperity of Genoa and Venice.
