He was seated with a party of gentlemen in the saloon of Sir William Hamilton's famous villa of Posilipo, where they were sipping the ambassador's iced sherbet and examining certain engraved gems and burial-urns recently taken from the excavations. The scene was such as always appealed to Odo's fancy: the spacious room, luxuriously fitted with carpets and curtains in the English style, and opening on a prospect of classical beauty and antique renown; in his hands the rarest specimens of that buried art which, like some belated golden harvest, was now everywhere thrusting itself through the Neapolitan soil; and about him men of taste and understanding, discussing the historic or mythological meaning of the objects before them, and quoting Homer or Horace in corroboration of their guesses. Several visitors had joined the party since Odo's entrance; and it was from a group of these later arrivals that the voice had reached him. He looked round and saw a man of refined and scholarly appearance, dressed en abbe, as was the general habit in Rome and Naples, and holding in one hand the celebrated blue vase cut in cameo which Sir William had recently purchased from the Barberini family. "These reliefs," the stranger was saying, "whether cut in the substance itself, or afterward affixed to the glass, certainly belong to the Grecian period of cameo-work, and recall by the purity of their design the finest carvings of Dioskorides." His beautifully-modulated Italian was tinged by a slight foreign accent, which seemed to connect him still more definitely with the episode his voice recalled. Odo turned to a gentleman at his side and asked the speaker's name. "That," was the reply, "is the abate de Crucis, a scholar and cognoscente, as you perceive, and at present attached to the household of the Papal Nuncio." Instantly Odo beheld the tumultuous scene in the Duke's apartments, and heard the indictment of Heiligenstern falling in tranquil accents from the very lips which were now, in the same tone, discussing the date of a Greek cameo vase. Even in that moment of disorder he had been struck by the voice and aspect of the agent of the Holy Office, and by a singular distinction that seemed to set the man himself above the coil of passions in which his action was involved. To Odo's spontaneous yet reflective temper there was something peculiarly impressive in the kind of detachment which implies, not obtuseness or indifference, but a higher sensitiveness disciplined by choice. Now he felt a renewed pang of regret that such qualities should be found in the service of the opposition; but the feeling was not incompatible with a wish to be more nearly acquainted with their possessor.
