This marble head is a bust of an original sculpture; 

The Hermes of the Museo Pio-Clementino. Part of the Vatican collections, Rome, the sculpture was long admired as the Belvedere Antinous, named from its prominent placement in the Cortile del Belvedere. It is now inventory number 907 in the Museo Pio-Clementino. This was a restored cast of the original sculpture done by an unknown artist which is now on permanent display at the Gardens of the Palace of Versailles, France.

Its idealized face is not in fact that of Antinous, the Emperor Hadrian's beloved. The cloak known as a chlamys, thrown over the left shoulder and wrapped round the left forearm, and the relaxed contrapposto identify the sculpture as a Hermes, one of a familiar Praxitelean type. Today the sculpture is considered (in the most recent Helbig) to be a Hadrianic copy (early second century CE) of a bronze by Praxiteles or one of his school.
