They stopped before the gate. It was a mighty thing. From its construction Carthoris could but dimly speculate upon its unthinkable antiquity.
It was circular, closing a circular aperture, and the Heliumite knew from his study of ancient Barsoomian architecture that it rolled to one side, like a huge wheel, into an aperture in the wall.
Even such world-old cities as ancient Aaanthor were as yet undreamed of when the races lived that built such gates as these.
As he stood speculating upon the identity of this forgotten city, a voice spoke to them from above. Both looked up. There, leaning over the edge of the high wall, was a man.
His hair was auburn, his skin fair-fairer even than that of John Carter, the Virginian. His forehead was high, his eyes large and intelligent.
The language that he used was intelligible to the two below, yet there was a marked difference between it and their Barsoomian tongue.
"Who are you?" he asked. "And what do you here before the gate of Lothar?"
"We are friends," replied Carthoris. "This be the princess, Thuvia of Ptarth, who was captured by the Torquasian horde. I am Carthoris of Helium, Prince of the house of Tardos Mors, Jeddak of Helium, and son of John Carter, Warlord of Mars, and of his wife, Dejah Thoris."
"`Ptarth`?" repeated the man. "`Helium`?" He shook his head. "I never have heard of these places, nor did I know that there dwelt upon Barsoom a race of thy strange colour. Where may these cities lie, of which you speak? From our loftiest tower we have never seen another city than Lothar."
Carthoris pointed toward the north-east.
"In that direction lie Helium and Ptarth," he said. "Helium is over eight thousand haads from Lothar, while Ptarth lies nine thousand five hundred haads north-east of Helium."
<1 <1 On Barsoom the AD is the basis of linear measurement. It is the equivalent of an Earthly foot, measuring about 11.694 Earth inches. As has been my custom in the past, I have generally translated Barsoomian symbols of time, distance, etc., into their Earthly equivalent, as being more easily understood by Earth readers. For those of a more studious turn of mind it may be interesting to know the Martian table of linear measurement, and so I give it here: 10 sofads = 1 ad 200 ads = 1 haad 100 haads = 1 karad 360 karads = 1 circumference of Mars at equator. A haad, or Barsoomian mile, contains about 2,339 Earth feet. A karad is one degree. A sofad about 1.17 Earth inches. Still the man shook his head. "I know of nothing beyond the Lotharian hills," he said. "Naught may live there beside the hideous green hordes of Torquas. They have conquered all Barsoom except this single valley and the city of Lothar. Here we have defied them for countless ages, though periodically they renew their attempts to destroy us. From whence you come I cannot guess unless you be descended from the slaves the Torquasians captured in early times when they reduced the outer world to their vassalage; but we had heard that they destroyed all other races but their own." Carthoris tried to explain that the Torquasians ruled but a relatively tiny part of the surface of Barsoom, and even this only because their domain held nothing to attract the red race; but the Lotharian could not seem to conceive of anything beyond the valley of Lothar other than a trackless waste peopled by the ferocious green hordes of Torquas. After considerably parleying he consented to admit them to the city, and a moment later the wheel-like gate rolled back within its niche, and Thuvia and Carthoris entered the city of Lothar. All about them were evidences of fabulous wealth. The facades of the buildings fronting upon the avenue within the wall were richly carven, and about the windows and doors were ofttimes set foot-wide borders of precious stones, intricate mosaics, or tablets of beaten gold bearing bas-reliefs depicting what may have been bits of the history of this forgotten people. He with whom they had conversed across the wall was in the avenue to receive them. About him were a hundred or more men of the same race. All were clothed in flowing robes and all were beardless. Their attitude was more of fearful suspicion than antagonism. They followed the new-comers with their eyes; but spoke no word to them. Carthoris could not but notice the fact that though the city had been but a short time before surrounded by a horde of bloodthirsty demons yet none of the citizens appeared to be armed, nor was there sign of soldiery about. He wondered if all the fighting men had sallied forth in one supreme effort to rout the foe, leaving the city all unguarded. He asked their host. The man smiled. "No creature other than a score or so of our sacred banths has left Lothar to-day," he replied. "But the soldiers-the bowmen!" exclaimed Carthoris. "We saw thousands emerge from this very gate, overwhelming the hordes of Torquas and putting them to rout with their deadly arrows and their fierce banths." Still the man smiled his knowing smile. "Look!" he cried, and pointed down a broad avenue before him. Carthoris and Thuvia followed the direction indicated, and there, marching bravely in the sunlight, they saw advancing toward them a great army of bowmen. "Ah!" exclaimed Thuvia. "They have returned through another gate, or perchance these be the troops that remained to defend the city?" Again the fellow smiled his uncanny smile. "There are no soldiers in Lothar," he said. "Look!" Both Carthoris and Thuvia had turned toward him while he spoke, and now as they turned back again toward the advancing regiments their eyes went wide in astonishment, for the broad avenue before them was as deserted as the tomb. "And those who marched out upon the hordes to-day?" whispered Carthoris. "They, too, were unreal?" The man nodded. "But their arrows slew the green warriors," insisted Thuvia. "Let us go before Tario," replied the Lotharian. "He will tell you that which he deems it best you know. I might tell you too much." "Who is Tario?" asked Carthoris. "Jeddak of Lothar," replied the guide, leading them up the broad avenue down which they had but a moment since seen the phantom army marching. For half an hour they walked along lovely avenues between the most gorgeous buildings that the two had ever seen. Few people were in evidence. Carthoris could not but note the deserted appearance of the mighty city. At last they came to the royal palace. Carthoris saw it from a distance, and guessing the nature of the magnificent pile wondered that even here there should be so little sign of activity and life. Not even a single guard was visible before the great entrance gate, nor in the gardens beyond, into which he could see, was there sign of the myriad life that pulses within the precincts of the royal estates of the red jeddaks. "Here," said their guide, "is the palace of Tario." As he spoke Carthoris again let his gaze rest upon the wondrous palace. With a startled exclamation he rubbed his eyes and looked again. No! He could not be mistaken. Before the massive gate stood a score of sentries. Within, the avenue leading to the main building was lined on either side by ranks of bowmen. The gardens were dotted with officers and soldiers moving quickly to and fro, as though bent upon the duties of the minute. What manner of people were these who could conjure an army out of thin air? He glanced toward Thuvia. She, too, evidently had witnessed the transformation. With a little shudder she pressed more closely toward him. "What do you make of it?" she whispered. "It is most uncanny." "I cannot account for it," replied Carthoris, "unless we have gone mad." Carthoris turned quickly toward the Lotharian. The fellow was smiling broadly. "I thought that you just said that there were no soldiers in Lothar," said the Heliumite, with a gesture toward the guardsmen. "What are these?" "Ask Tario," replied the other. "We shall soon be before him." Nor was it long before they entered a lofty chamber at one end of which a man reclined upon a rich couch that stood upon a high dais. As the trio approached, the man turned dreamy eyes sleepily upon them. Twenty feet from the dais their conductor halted, and, whispering to Thuvia and Carthoris to follow his example, threw himself headlong to the floor. Then rising to hands and knees, he commenced crawling toward the foot of the throne, swinging his head to and fro and wiggling his body as you have seen a hound do when approaching its master. Thuvia glanced quickly toward Carthoris. He was standing erect, with high-held head and arms folded across his broad chest. A haughty smile curved his lips. The man upon the dais was eyeing him intently, and Carthoris of Helium was looking straight in the other`s face. "Who be these, Jav?" asked the man of him who crawled upon his belly along the floor. "O Tario, most glorious Jeddak," replied Jav, "these be strangers who came with the hordes of Torquas to our gates, saying that they were prisoners of the green men. They tell strange tales of cities far beyond Lothar." "Arise, Jav," commanded Tario, "and ask these two why they show not to Tario the respect that is his due." Jav arose and faced the strangers. At sight of their erect positions his face went livid. He leaped toward them. "Creatures!" he screamed. "Down! Down upon your bellies before the last of the jeddaks of Barsoom!"
