The fourth is filled with the heads of illustrious persons, and a variety of inscriptions. On one of which, Seraspandes and Rhodaspes, the sons of Phraates, are mentioned; and it is particularly valued because Justin, the only Roman historian who takes notice of these Princes being at Rome, omitted their names. The fifth contains a beautiful statue of an hermaphrodite, which gives name to the chamber; an Adonis, by Michael Angelo; Venus Victrix; Venus Celeste, and a Bacchus. All excellent statues; and near fifty valuable paintings. The present Grand Duke fitted up the sixth hall for the reception of Niobe, and her fourteen children, with a taste and magnificence worthy these admirable statues. The collection of old paintings in the next room is also the work of the reigning Prince. They are accompanied by several busts and statues. The eighth contains copies in bronze, not only of the Venus of Medicis, and the most admired pieces in the preceding apartments, but of every other celebrated statue, of which the Dukes of Florence have not been able to procure the original. Among these are the _Quirinal_ group of horses; the _Capitol_ Gladiator; the _Vatican_ Apollo, and Meleagre; the little _Spanish_ fawn; the _Farnese_ Hercules, Bull, and Flora, and many others, which the severest critics have allowed to be equal to the originals. But it is not copies only which here ravish the sight. John Bologna's incomparable Mercury soon arrests the eye. He is absolutely flying, and in so easy, and so natural an attitude, that it is some moments before one perceives that he is supported by the breath of Zephyr, on which he is rising into the air. From this we pass into the cabinet of bronze antiques, where a variety of miniature Gods and Goddesses, animals, and monsters; altars, tripods, and lamps; helmets, rings, and bracelets, &c. &c. are preserved in fourteen cases. We now close the Gallery with the Tuscan Museum, whose chief contents are the instruments used by the ancients in their funeral ceremonies, with a variety of urns, in which the burnt bones of the dead were deposited. There let them rest in peace, and if sleep has not already overpowered you, indulge it now--I shall not be offended with you. I am aware, that however refined and extatic the satisfaction, the objects I have mentioned afford to the senses, this pleasure is not to be communicated in a description by so humble a Dilettante as your poor friend. I have, therefore, nearly confined myself to an abridgment of the catalogue, which, as I before apprised you, fills a large volume. And since a long list, even of painters, and sculptors, statues, and paintings, must ever be dry and tautological, what can we expect from its epitome? But to me, I confess, it has afforded the greatest satisfaction; that of proving that to please you, I willingly risk exposing myself. LETTER XXIV. TO CAPTAIN SMITH.
