Giambologna : Hercules Slaying a Centaur - Loggia dei Lanzi

"This sculptural group was first placed, in 1599, on the Canto dei Carnesecchi in Florence, then it was moved under the loggia of the Uffizi, on the southern side; later it was placed on the small square near the Ponte Vecchio, on the left bank of the Arno and, in 1812, it found its final seat in the Loggia dei Lanzi in Piazza della Signoria.
It was sculpted from one solid block of white marble with the help of Pietro Francavilla." wikipedia
