The statues of both the Chimera and Minerva come from Arezzo. The Chimera was discovered in 1553 while they were digging ditches for new city walls. It is a truly splendid work from the 5th century BC, strongly dynamic, with great expressive power, and the bronze was cast using the very best of techniques.

It is a statue of the mythological monster caught in the act of snarling at the hero, Bellerophon, who has mortally wounded it. The statue was probably one of a group of votive statues which formed part of the treasury of an important temple. There is an inscription on one of the creature's paws which reads "Tins Cuil" meaning "gift to Tinia", in other words, to Jupiter. The Chimera was restored by the great sculptor Benvenuto Cellini when it was brought to Florence in 1554.
The statue of Minerva dates from the 4th century BC and is a reproduction of a Greek original. The lower part was missing, but was remade in bronze-colored plaster at the end of the 18th century. Although it has an indisputable visual fascination, the technique with which it was cast is undoubtedly inferior to that of the Chimera. The statue was found in Arezzo near the church of San Lorenzo in 1541.
The "Arringatore" or the Speaker in the Act of Haranguing – this is the name conventionally given to a beautiful portrait of the nobleman Aulus Metellus captured precisely while in the act of speaking in public. This magnificent Etruscan bronze from the 3rd century BC became the inspiration for a number of ancient Roman portrait statues. It was discovered in 1566 in Sanguineto, a village close to Trasimeno.
The "Idolino" is, instead, a Greek work from the 5th century BC. It shows a young athlete who, after winning his competition, is in the act of offering a libation to the gods. This work, with its total harmony and delicate technique, belongs to the Attic school and was discovered in Pesaro in 1530. Along with the rest of the legacy belonging to the Dukes of Urbino, the "Idolino" became part of the Medici collection after 1631.
