Here lolled some scattered groups of the populace, discussing the events of the day, jesting, gesticulating, drinking or love-making. Others roamed about, engaged in conversation or enjoying the antics of two Smyrniote tumblers, whose contortions elicited storms of applause from an appreciative audience. A crowd of maskers had invaded the Piazza Navona, and the uncommon spectacle at last drew Tristan from his point of vantage and caused him to mingle with the crowds, which increased with every moment, their shouts and gibes and the clatter of their tongues becoming quite deafening to his ears. Richly decorated chariots, drawn by spirited steeds, rolled past in a continuous procession. The cries of the wine-venders and fruit-sellers mingled with the acclaim of the multitudes. Now and then was heard the fanfare of a company of horsemen who clattered past, bound upon some feudal adventure. Weary of walking, distracted by the ever increasing clamor, oppressed with a sense of loneliness amidst the surging crowds, whose festal spirit he did not share, Tristan made his way towards the fountain and, seating himself on the margin, regardless of the chattering groups, which intermittently clustered about it, he felt his mood gradually calm in the monotony of the gurgling flow of the water, which spurted from the grotesque mouths of lions and dolphins. The stars sparkled in subdued lustre above the dark, towering cypresses which crowned the adjacent eminence of Monte Testaccio, and the distant palaces and ruins stood forth in distinctness of splendor and desolation beneath the luminous brightness of the moonlit heavens. White shreds of mist, like sorrowing spirits, floated above the winding course of the Tiber, and enveloped in a diaphanous haze the cloisters upon St. Bartholomew's Island at the base of Mount Aventine. For a time Tristan's eyes roamed over the kaleidoscopic confusion which met his gaze on every turn. His ear was assailed by the droning sound of many voices that filled the air about him, when he was startled by the approach of two men, who, but for their halting gait, might have passed unheeded in the rolling sea of humanity that ebbed and flowed over the Piazza. Basil, the Grand Chamberlain, was endowed with the elegance of the effeminate Roman noble of his time. Supple as an eel, he nevertheless suggested great physical strength. The skin was of a deep olive tinge. The black, beady eyes were a marked feature of the countenance. Inscrutable and steadfast in regard, with a hint of mockery and cynicism, coupled with an abiding alertness, they seemed to penetrate the very core of matter.
