An hour later, in a high vaulted, dimly lighted chamber of the Archangel's Castle, Tristan, the pilgrim, and Alberic, the Senator of Rome, faced each other for the second time. In the course of the pursuit of the ruffians in which he participated, Tristan had been casually informed of the rank of him who led the Senatorial guard in person and when, their object accomplished, he started to detach himself from the men-at-arms, Alberic had foiled his intention by commanding him to accompany him to the fortress-tomb where he himself held forth. Seated opposite each other, each seemed to scan the other's countenance before a word was spoken between them. Alberic's regard of the man who seemed utterly unconscious of the importance of the service he had rendered the Senator betokened approval, and his eyes dwelt for some moments on the frank and open countenance of this stranger, perchance contrasting it inwardly with the complex nature of those about his person in whom he could trust but so long as he could tempt them with earthly dross, and who would turn against him should a higher bidder for their favor appear. Tristan's first impression of the son of Marozia was that of one born to command. Dark piercing eyes were set in a face, stern, haughty, yet strangely beautiful. Alberic's tall, slender figure, dressed in black velvet, relieved by slashes of red satin, added to the impressiveness of his personality. Upon closer scrutiny Tristan could discover a marked resemblance between the man before him and his half-brother, the ill-fated Pontiff, whom, for political reasons, or considerations of his personal safety, he kept prisoner in the pontifical palace. But there was yet another present, who apparently took little heed of the stranger, engaged as he seemed in the perusal of a parchment, spread out upon a table before him,--Basil, the Grand Chamberlain. A whispered conversation had taken place between the Senator and his confidential adviser, for this was Basil's true station in the senatorial household. In the evil days of Marozia's regime he had occupied the same favored position at the Roman court, and, when Alberic's revolt had swept the regime of Ugo of Tuscany and Marozia from Roman soil, the son had attached to himself the man who had shown a marked sagacity and ability in the days that had come to a close. Basil's complex countenance proved somewhat more of an enigma to the silent on-looker than did the Senator's stern, though frank face. He was garbed in black, a color to which he seemed partial. A flat cap of black velvet with a feather curled round the brim, above a doublet of black velvet, close fitting, the sleeves slashed, to show the crimson tunic underneath. The trunk hose round the muscular legs were of black silk and gold thread, woven together and lined with sarsenet. His feet were encased in black buskins with silver buckles, and puffed silk inserted in the slashings of the leather.
