worshippers of Jupiter. Among the statues wrought of this marble may be mentioned the famous group of the Laocoon found in the Baths of Titus; the beautiful Venus de Medici, discovered in the Villa of Hadrian, near Tivoli, and now in the Uffizi Gallery in Florence; and the well-known "Farnese Bull," sculptured out of a single block of huge dimensions, unearthed out of the ruins of the Baths of Caracalla, and now in the Museum of Naples. Massimo d'Azeglio, in his _Recollections_, gives an interesting instance of the value set upon this marble by modern Roman sculptors. Pacetti having purchased an ancient Greek statue of the best period in Pentelic marble, greatly mutilated, and wishing to repair it, could find nothing among the best products of the Carrara quarries to match the marble in purity and fineness of texture, and was therefore obliged to destroy another Greek statue of inferior merit in order to get materials for the restoration. From this combination he succeeded in producing the sleeping figure known as the Barberini Faun, whose forcible abduction by the Pontifical Government on the eve of its being sold to a German prince, so preyed upon the mind of the cruelly-wronged sculptor, that he took to his bed and died. Very like Pentelic marble, but easily distinguishable, is the Marmor Porinum, the Marmo Grechetto duro of the Italians. It is intermediate in the quality of its grain between Parian and Pentelic marble, being finer than the former and not so fine as the latter. The column in front of the Church of Santa Maria Maggiore, removed by Paul V. in 1614 from the Basilica of Constantine, is composed of this species; as well as the celebrated Torso Belvedere of the Vatican, found near the site of the Theatre of Pompey, to which Michael Angelo traced much of his inspiration, and which, as we learn from a Greek Inscription at the base, was the work of the Rhodian sculptor Apollonios, who carved the group of the "Farnese Bull."
