Hermes and the Infant Dionysus, also known as the Hermes of Praxiteles or the Hermes of Olympia is an ancient Greek sculpture of Hermes and the infant Dionysus discovered in 1877 in the ruins of the Temple of Hera, Olympia, in Greece. It is displayed at the Archaeological Museum of Olympia.
It is traditionally attributed to Praxiteles and dated to the 4th century BC, based on a remark by the 2nd century Greek traveller Pausanias, and has made a major contribution to the definition of Praxitelean style. Its attribution is, however, the object of fierce controversy among art historians.
The sculpture is unlikely to have been one of Praxiteles' famous works, as no ancient replicas of it have been identified. The documentary evidence associating the work with Praxiteles is based on a passing mention by the 2nd-century AD traveller Pausanias.
In 1874, the Greek state signed an agreement with Germany for an archaeological exploration of the Olympia site, which was first dug in the French Morea expedition of 1829. The German excavations in 1875 were led by Ernst Curtius. On 8 May 1877, in the temple of Hera, he uncovered the body (head, torso, legs, left arm) of a statue of a young man resting against a tree trunk covered by a mantle. Protected by the thick clay layer above it, it was in an exceptionally good state of preservation.
It took six more separate discoveries to uncover the rest of the statue as it is displayed today. Hermes is still missing his right forearm, two fingers of his left hand, both forearms below the elbow, the left foot and his penis, whilst Dionysus is missing his arms (except the right hand on Hermes's shoulder) and the end of his right foot. Much of the tree trunk and the plinth are also lost. However, an ancient base survives, made of a grey limestone block between two blocks of marble.
The group is sculpted from a block of the best quality of Parian marble. Hermes measures 2.10/2.12 m, 3.70 m with the base. The right foot of Hermes is integral with a section of the base, which has undergone some adjustment in antiquity.
