The temple itself was really a part of the palace and similar in architecture. There were several ceremonial places of varying sizes, the purposes of which Tarzan could only conjecture. Each had an altar in the west end and another in the east and were oval in shape, their longest diameter lying due east and west. Each was excavated from the summit of a small hillock and all were without roofs. The western altars invariably were a single block of stone the top of which was hollowed into an oblong basin. Those at the eastern ends were similar blocks of stone with flat tops and these latter, unlike those at the opposite ends of the ovals were invariably stained or painted a reddish brown, nor did Tarzan need to examine them closely to be assured of what his keen nostrils already had told him--that the brown stains were dried and drying human blood. Below these temple courts were corridors and apartments reaching far into the bowels of the hills, dim, gloomy passages that Tarzan glimpsed as he was led from place to place on his tour of inspection of the temple. A messenger had been dispatched by Ko-tan to announce the coming visit of the son of Jad-ben-Otho with the result that they were accompanied through the temple by a considerable procession of priests whose distinguishing mark of profession seemed to consist in grotesque headdresses; sometimes hideous faces carved from wood and entirely concealing the countenances of their wearers, or again, the head of a wild beast cunningly fitted over the head of a man. The high priest alone wore no such head-dress. He was an old man with close-set, cunning eyes and a cruel, thin-lipped mouth. At first sight of him Tarzan realized that here lay the greatest danger to his ruse, for he saw at a glance that the man was antagonistic toward him and his pretensions, and he knew too that doubtless of all the people of Pal-ul-don the high priest was most likely to harbor the truest estimate of Jad-ben-Otho, and, therefore, would look with suspicion on one who claimed to be the son of a fabulous god. No matter what suspicion lurked within his crafty mind, Lu-don, the high priest of A-lur, did not openly question Tarzan's right to the title of Dor-ul-Otho, and it may be that he was restrained by the same doubts which had originally restrained Ko-tan and his warriors--the doubt that is at the bottom of the minds of all blasphemers even and which is based upon the fear that after all there may be a god. So, for the time being at least Lu-don played safe. Yet Tarzan knew as well as though the man had spoken aloud his inmost thoughts that it was in the heart of the high priest to tear the veil from his imposture.
