are sculptures by Bandinelli: in the center the statue of the seated "Leo X" (sculpted assisted by his student Vincenzo de'Rossi), and on the right a statue of "Charles V crowned by Clement VII". The six statues along the walls that represent the "Labors of Hercules" are by de' Rossi. In the central niche at the south of the Hall is Michelangelo's noted marble group The Genius of Victory (1533–1534), originally intended for the tomb of Julius II. The statue was placed in this hall by Vasari. In 1868 it was removed to the Bargello Museum, but was returned in 1921 by officials. Studiolo of Francesco I At the end of the hall is a small side room without windows. The studiolo was a small secret study designed by Vasari in a manneristic style (1570–1575). The walls and the barrel vault are filled with paintings, stucco and sculptures. Most paintings are by the School of Vasari and represent the four elements: fire, water, earth, and air. The portrait of Cosimo I and his wife Eleonora of Toledo was painted by Bronzino. The delicate bronze sculptures were made by Giambologna and Bartolomeo Ammanati. From a peep-hole, Francesco spied on his ministers and officers during meetings in the Salone dei Cinquecento. Dismantled within decades of its construction, it was re-assembled in the 20th century. The other rooms on the first floor are the Quartieri monumentali. These rooms, the Residence of the Priors and the Quarters of Leo X, are used by the mayor as offices and reception rooms. They are not accessible to the public. Second Floor A staircase designed by Vasari leads to the second floor. This floor contains the Apartments of the Elements, Priori, and Eleonora of Toledo. Apartments of the Elements These apartments (Sala degli Elementi) consist of five rooms (such as the Room of Ceres) and two loggias. The commission for these rooms was originally given by Cosimo I to Giovanni Battista del Tasso. But on his death, the decorations were continued by Vasari and his helpers, working for the first time for the Medicis. These rooms were the private quarters of Cosimo I. Room of the Elements The walls in the Room of the Elements are filled with allegorical frescoes Allegories of Water, Fire and Earth and, on the ceiling, represents Saturn. The original statue "Boy with a Fish" by Verrocchio is on exhibit in one of
