I have digressed from my connected narrative—perhaps in the vain hope of evading the telling of that final incident; that incident which of all is most certainly an hallucination. But I promised to relate it, and do not break promises. When I recovered—or seemed to recover—my senses after that fall down the black stone stairs, I was quite as alone and in darkness as before. The windy stench, bad enough before, was now fiendish; yet I had acquired enough familiarity by this time to bear it stoically. Dazedly I began to crawl away from the place whence the putrid wind came, and with my bleeding hands felt the colossal blocks of a mighty pavement. Once my head struck against a hard object, and when I felt of it I learned that it was the base of a column—a column of unbelievable immensity—whose surface was covered with gigantic chiseled hieroglyphics very perceptible to my touch. Crawling on, I encountered other titan columns at incomprehensible distances apart; when suddenly my attention was captured by the realization of something which must have been impinging on my subconscious hearing long before the conscious sense was aware of it.
