PLZZ HURRY What potential problems did the systems of patronage solve? during Renaissance in italy

When the banker’s guild of Florence commissioned a massive bronze statue of St. Matthew for Orsanmichele—a former grain house turned shrine at the heart of the city—they clearly had their own magnificence in mind. Not only did they hire the highly in-demand sculptor, Lorenzo Ghiberti, to create it, but they also stipulated in the work’s contract that it must be as big or bigger than the sculptor’s creation for a rival guild in the same location. They also wanted it to be cast from no more than two pieces (a difficult feat!). Ghiberti’s fame, the statue’s scale, and the technical proficiency required to cast it were all reflections of the banker’s guild’s own status.

God bless!
