The head does not belong to this statue. 428, the Crouching Venus, a copy after Heliodorus, by Bupalus; 429, the Empress Sabina, Hadrian's wife, as Venus Genetrix, after Arcesilaus.

The court is adorned with baths, urns, sarcophagi, statues, columns, bas-reliefs, and medallions. The four corners of the court are occupied by cabinets _in the following order, commencing on the left_:-- MERCURY OF THE BELVEDERE. A most valuable piece of antique Greek sculpture, found near the Baths of Titus in 1779. On the walls are bas-reliefs representing a combat between Amazons and Athenians, and a sacred procession; 56, Priapus, the god of orchards; 57, Hercules. CANOVA'S CABINET. It contains three splendid works by this great modern master: Perseus with the Head of Medusa; the Two Boxers, Kreugas (defence), Damoxenus (attack). APOLLO BELVEDERE. One of the finest masterpieces of ancient Greek sculpture, discovered at Porto d'Anzio towards the close of the fifteenth century--Apollo in the attitude of turning the army of the Gauls into stone, with the head of Medusa, B.C. 278, as we are informed by the inscription in bronze; it was restored erroneously. It is beautifully described by Byron in "Childe Harold." CABINET OF THE LAOCOON. Found in the Baths of Titus in 1506. Pliny (xxxvi. 4) thus describes it:--"A work which may be considered superior to all others both in painting and statuary. The whole group--the father, the boys, and the awful folds of the serpents--were formed out of a single block by Agesander, Polydorus, and Athenodorus, natives of Rhodes. Michael Angelo said, however, and it has since been proved, that it is in three pieces."
