Tristan of Avalon was in his thirtieth year, though the hardships of a long and tedious journey, consummated entirely afoot, made him appear of maturer age. The face, long exposed to the relentless rays of the sun, had taken on the darker tints of the Southland. The nose was straight, the grey eyes tinged with melancholy, the hair was of chestnut brown, the forehead high and lofty. The ensemble was that of one who, unaccustomed to the pilgrim's garb, moves uneasily among his kind. Yet the atmosphere of frivolity, while irritating and jarring upon his senses, did not permit him to avert his gaze from the orgy of color, the pandemonium of jollity, that whirled and piped and roared about him as the flow of mighty waters. One of many strange wayfarers bound upon business of one sort or another to the ancient seat of empire, whose worldly sceptre had long passed from her palsied grip to the distant shores of the Bosporus, Tristan had arrived during the early hours of the day in the feudal and turbulent witches' cauldron of the Rome of the Millennium. And with him constituents of many peoples, from far and near, had reached the Leonine quarter from the Tiburtine road, after months of tedious travel, to worship at the holy shrines, to do penance and to obtain absolution for real or imaginary transgressions. From Bosnia, from Servia and Hungary, from Negropont and the islands of the Greek Archipelago, from Trebizond and the Crimea it came endlessly floating to the former capital of the Cæsars, a waste drift of palaces and temples and antique civilizations, for the End of Time was said to be nigh, and the dread of impending judgment lay heavily upon the tottering world of the Millennium. A grotesque and motley crowd it was, that sought and found a temporary haven in the lowly taverns, erected for the accommodation of perennial pilgrims, chiefly mean ill-favored dwellings of clay and timber, divided into racial colonies, so that pilgrims of the same land and creed might dwell together. A very Babel of voices assailed Tristan's ear, for the ancient sonorous tongue had long degenerated into the lingua Franca of bad Latin, though there were some who could still, though in a broken and barbarous fashion, make themselves understood, when all other modes of expression failed them. All about him throbbed the strange, weird music of zitherns and lutes and the thrumming of the Egyptian Sistrum. The air of the summer night was heavy with the odor of incense, garlic and roses. The higher risen moon gleamed pale as an alabaster lamp in the dark azure of the heavens, trembling luminously on the waters of a fountain which occupied the centre of the Piazza Navona.
