The Peruzzi were bankers of Florence, among the leaing families of the city in the 14th century, before the rise to prominence of the Medici. Their modest antecedents stretched back to the mid 11th century, according to the family's genealogist Luigi Passerini, but a restructuring of the Peruzzii company in 1300, with an infusion of outside capital, marked the start of a quarter-century of prosperity that brought the family consortium to the forefront of Florentine affairs. Semi-public patronage reaffirmed the Peruzzi status in Florence: in his will in 1299, Donato di Arnoldo Peruzzi left money for a memorial chapel in a transept of the Basilica of Santa Croce, Florence. It was probably his grandson Giovanni di Rinieri Peruzzi who was Giotto's patron in frescoing the walls with murals honoring John the Evangelist and John the Baptist, which Giotto executed, starting in 1313.
