The correct answer to this open question is the following.
Although there is no text attached or any further reference to it, we can say that Italy's states became important cultural centers during the Renaissance because rich and prominent Italian families such as the Medici, sponsored many artists during the Renaissance. The Medici were the most powerful family in the city-state of Florence. They sponsored the work of artists such as Leonardo Da Vinci.
During the Renaissance, other important artists flourished, as was the case of the magnificent Michel Angelo Buonarroti, creator of the ceiling paintings of the Sixtine Chapel or the figure known as "La Pieta."
