"No white man has entered this country," replied the officer, "since Marcus Crispus Sanguinarius led the Third Cohort of the Tenth Legion in victorious conquest of the barbarians who inhabited it eighteen hundred and twenty-three years ago." "And if a stranger were in your country you would know it?" asked Tarzan. "If he were in Castra Sanguinarius, yes," replied the officer, "but if he had entered Castrum Mare at the east end of the valley I should not know it; but come, I was not sent here to answer questions, but to fetch you before one who will ask them." At a word from the officer, the soldiers who accompanied him conducted Tarzan from the dungeon, along the corridor through which he had come the previous day and up into the city. The detachment proceeded for a mile through the city streets to an imposing building, before the entrance to which there was stationed a military guard whose elaborate cuirasses, helmets, and crests suggested that they might be a part of a select military organization. The metal plates of their cuirasses appeared to Tarzan to be of gold, as did the metal of their helmets, while the hilts and scabbards of their swords were elaborately carved and further ornamented with colored stones ingeniously inlaid in the metal, and to their gorgeous appearance was added the final touch of scarlet cloaks. The officer who met the party at the gate admitted Tarzan, the black interpreter, and the officer who had brought him, but the guard of soldiery was replaced by a detachment of resplendent men-at-arms similar to those who guarded the entrance to the palace. Tarzan was taken immediately into the building and along a wide corridor, from which opened many chambers, to a large, oblong room flanked by stately columns. At the far end of the apartment a large man sat in a huge, carved chair upon a raised dais. There were many other people in the room, nearly all of whom were colorfully garbed in bright cloaks over colored tunics and ornate cuirasses of leather or metal, while others wore only simple flowing togas, usually of white. Slaves, messengers, officers were constantly entering or leaving the chamber. The party accompanying Tarzan withdrew between the columns at one side of the room and waited there. "What is this place?" asked Tarzan of the Bagego interpreter, "and who is the man at the far end of the room?" "This is the throne-room of the Emperor of the West and that is Sublatus Imperator himself." For some time Tarzan watched the scene before him with interest. He saw people, evidently of all classes, approach the throne and address the Emperor, and though he could not understand their words, he judged that they were addressing pleas to their ruler. There were patricians among the supplicants, brown-skinned shopkeepers, black barbarians resplendent in their savage finery, and even slaves.
