Located in the center of Florence, the Bargello Museum is one of the oldest buildings in Florence and the second largest national museum in Florence. God and Donatello's David. The Bargello Museum is a tall building with a bell tower. This building began in 1255, and was originally the seat of the municipal government of Florence, so it was also called the People's Palace, and later became the headquarters of the police force, and Bargello was the name of a police force chief. In the 18th century, it was turned into a prison where the unfortunate people were tortured and sanctioned. In 1865, it was changed to the National Museum of Italy, and later became an art gallery. The first thing you see when you enter the art gallery is a courtyard, where various sculptures are placed, such as the Venus fountain, the emperor's coronation, and the cannon of St. Paul with the head of St. Paul. The pattern on the ceiling of the corridor is very interesting and is drawn with the large satellite as the basic element. There is a well in the courtyard, which used to be the gallows, where the prisoners would be escorted to be tried. The first floor is dominated by works from the late 15th century to the 16th century, including Michelangelo's Bacchus. It is said that this is the first work Michelangelo was commissioned when he debuted at the age of 21. The god of wine here is holding a wine glass in his hand, and he seems to have a bunch of fresh grapes on his head, and he looks very drunk. Another of Michelangelo's works, the bas-relief "The Virgin and Child" that he completed early, is also here. This is a disc with the Virgin and Infant Saint John carved on it. In addition, there is Giambologna's "Mercury" in the exhibition hall. Mercury in the sculpture was a messenger of messages to the gods and a protector of medicine, travelers, merchants, and thieves. Most of his images are of a hat with wings on his head, flying shoes with wings on his feet, and holding a wand wrapped around two snakes. There is also a bust of Bernini based on his mistress. The second floor displays works from the late 14th century to the 15th century, represented by the works of Donatello, the author of "The Statue of David". On the second floor is a bronze statue of David from 1430-1432, said to be the first to revive the ancient tradition of nude statues. The muscles of this David are very relaxed, the lines are clear, and the structure of the human body is reasonable. He is completely the image of a childish teenager, with elegant posture and vivid expression. There is a platform outside the exhibition hall on the second floor, where there are many small sculptures, which are said to have been moved from the Medici villa. From the platform, you can look up to see the bell tower and the jagged roof. The walls are mottled and dark, and the heaviness of history is reflected here. On the third floor there is a room with glazed ceramics by the sculptor Giovanni della Robbia, and a room named after the sculptor Verrozio, which displays his bronze "David" Portrait" and many Florentine portraits by 15th-century artists. Of course, the medals, textiles, tapestries, ivory fabrics, silverware, armor and coins of the Medici family can also be admired here.
