From the platform I could see through the mouth of Tur. Below me was a large chamber along the sides of which were ranged other, though lesser, idols. They were even more grotesque than those I had seen in the temple in the city and their trappings were rich beyond the conception of man—Earthman—for the gems of Barsoom scintillate with rays unknown to us and of such gorgeous and blinding beauty as to transcend description. Directly in front of the Great Tur was an altar of palthon, a rare and beautiful stone, blood red, in which are traced in purest white Nature’s most fanciful designs; the whole vastly enhanced by the wondrous polish which the stone takes beneath the hand of the craftsman. Gor Hajus joined me and together we examined the interior of the temple. Tall windows lined two sides, letting in a flood of light. At the far end, opposite the Great Tur, were two enormous doors, closing the main entrance to the chamber, and here stood the two priests whom we had heard conversing. Otherwise the temple was deserted. Incense burned upon tiny altars before each of the minor idols, but whether any burned before the Great Tur we could not see. Having satisfied our curiosity relative to the temple, we returned our attention to a further examination of the interior of Tur’s huge head and were rewarded by the discovery of another ladder leading upward against the rear wall to a higher and smaller platform that evidently led to the eyes. It did not take me long to investigate and here I found a most comfortable chair set before a control that operated the eyes, so that they could be made to turn from side to side, or up or down, according to the whim of the operator; and here too was a speaking-tube leading to the mouth. This again I must needs investigate and so I returned to the lower platform and there I discovered a device beneath the tongue of the idol, and this device, which was in the nature of an amplifier, was connected with the speaking-tube from above. I could not repress a smile as I considered these silent witnesses to the perfidy of man and thought of the broken thing lying at the foot of the ladder. Tur, I could have sworn, had been silent for many years. Together Gor Hajus and I returned to the higher platform and again I made a discovery—the eyes of Tur were veritable periscopes. By turning them we could see any portion of the temple and what we saw through the eyes was magnified. Nothing could escape the eyes of Tur and presently, when the priests began to talk again, we discovered that nothing could escape Tur’s ears, for every slightest sound in the temple came clearly to us. What a valuable adjunct to high priesthood this Great Tur must have been in the days when that broken skeleton lying below us was a thing of blood and life! CHAPTER XII THE GREAT TUR
