This is the Gaddi Torso, a fragmentary ancient Roman marble sculpture from the 2nd century BCE [750 X 1125]

The sculpture is believed to be a Roman copy of a lost Hellenistic bronze original, possibly depicting a centaur struggling against his bonds.
It is named after the Gaddi family of Florence, who owned it in the early 16th century.
The Gaddi Torso is housed in the Uffizi Gallery in Florence, Italy, and is admired for its detailed and powerful musculature.
The sculpture was a source of inspiration for many Renaissance artists, including Michelangelo.
