For what seemed miles the way led on and I began to think that the entrance was outside the valley and that I was being led to freedom, when a glimmer of light showed ahead, the floor sloped upward, and, an instant later, I emerged in the open air. For a moment my eyes were blinded by the light after the darkness of the passage and I could not grasp where I was. I had thought it evening, but my first glance told me it was early morning and I knew the night had passed and another day had come. Then, as I looked about at my surroundings and it dawned upon me where I was, a shudder of horror, a chill of deadly fear swept over me. I was on the summit of the pyramid. The sacrificial altar was within three paces. Beside it stood the fiendish priest and his assistants, and gathered upon the green plain were hordes of people with faces upturned towards me. I was about to be sacrificed, to be bound fast to the blood-stained awful stone, to have my still-beating heart torn from my living body! Anything were preferable to that and with a sudden bound I strove to gain the altar’s edge and hurl myself to certain death. But to no avail. Two of the dwarfs held me fast by the cord which fastened my wrists and I was jerked back to fall heavily upon the stones. Before I could struggle up, four of the priest’s assistants sprang forward and, grasping me by legs and shoulders, lifted me and tossed me upon the stinking sacrificial stone. I was helpless, and instantly my ankles were tied fast to the metal staples, the bonds of my wrists were severed, my arms were drawn apart and securely lashed to other staples, the stone collar was placed about my neck forcing my head far back and I was ready for the glowering priest to wreak his awful vengeance. Stepping close to the altar he drew a glittering obsidian knife—and even in my terrible predicament I noted this, and realized that he was adhering strictly to Aztec customs—and, raising his arms, he began a wailing, blood-curdling chant. Up from the thousands of throats below came the chanting chorus, rising and falling like a great wave of sound. How long I wondered, would this keep on? How much longer must this agony, this torture of suspense be borne? Why did he not strike his stone dagger into my chest and have it over with? And then, from some dormant cell in my brain, came the answer. I was to be sacrificed to the sun god, and I remembered that, according to the Aztec religion, the blow could not be struck until the rising sun cast its rays upon the victim’s chest above the heart. The priest was awaiting that moment. He was delaying until the sun, still behind the crater’s rim, should throw its first rays upon me.
