This museum is formed of the remains found in the excavations of the municipality since Rome was made the capital of united Italy. The new circular hall, designed by Signor Vespignani, presents a light and elegant effect. Amongst the most important subjects placed in the new hall, we may mention No. 2, the monument of Quintus Sulpicius Maximus, found in 1870 in the Old Porta Salaria. The inscription states that he died at the early age of thirteen years, five months, and twelve days. He carried off the honours for composing Greek verse against fifty-two competitors. The poem is engraved on the pilasters. The subject is--The arguments used by Jove in reproving Phœbus for intrusting his chariot to Phaeton. Africa's deserts and the negroes' black skins are ascribed to the careless driving of Phaeton on that occasion. No. 5. Venus. 23. Mercury. 11. A bust of Faustina the elder. 13. A youth anointing himself. 14 and 16. Tritons. 15. A half statue of the Emperor Commodus as Hercules, beautifully executed in fine marble, with the lion's skin over his head and knotted upon his chest: in his right hand is the club. A bracket of marble, ornamented at its end with a celestial globe, rested on the pedestal, which formed a shield, a band running round the centre with the signs of the zodiac. This bracket is supported by two kneeling figures, holding cornucopias containing fruit. One is in good preservation; the fragments of the other were also found. 17. Plotina, wife of Trajan. 18. Apollo. 19. Bacchus, with a satyr on a leopard at his side. 21. Sarcophagus of the Calydonian boar hunt. Polyhymnia. 24. Terpsichore. 26. A beautiful nude statue of a young girl or nymph leaving the bath, of Parian marble, standing with sandalled feet by a pedestal, which supports her robe, the left hand fastening up the hair. 28, 29. Two magistrates about to start the racers by dropping a handkerchief. They represent L. A. A. Symmachus, prefect of Rome, A.D. 365, and his son; and are unique. The father was found in one hundred and eighty pieces, and the son in ninety pieces, which have been carefully put together. 31. Colossal statue. 33. Fortune. Apollo with the Lyre.
