We are talking about a prominent member of the Medici family, Lorenzo de Medici, in Florence, one of the most powerful city-states in Italy during the Renaissance times.
Lorenzo de Medici was a powerful man, respected by all the citizens. Indeed, his presence and actions made him be known as "the Magnificent," in Florence. He described Rome as an important religious, political and artistic center. The Medici family was well known for the support they gave to many painters, sculptors, and artists, to create beautiful pieces of art during the Renaissance.
