As I lay still with closed eyes, free to ponder, many things I had lightly noted in the frescoes came back to me with new and terrible significance—scenes representing the nameless city in its heyday, the vegetation of the valley around it, and the distant lands with which its merchants traded. The allegory of the crawling creatures puzzled me by its universal prominence, and I wondered that it should be so closely followed in a pictured history of such importance. In the frescoes the nameless city had been shown in proportions fitted to the reptiles. I wondered what its real proportions and magnificence had been, and reflected a moment on certain oddities I had noticed in the ruins. I thought curiously of the lowness of the primal temples and of die underground corridor, which were doubtless hewn thus out of deference to the reptile deities there honored; though it perforce reduced the worshippers to crawling. Perhaps the very rites here involved a crawling in imitation of the creatures. No religious theory, however, could easily explain why the level passage in the awesome descent should be as low as the temples—or lower, since one could not even kneel in it. As I thought of the crawling creatures, whose hideous mummified forms were so close to me, I felt a new throb of fear. Mental associations are curious, and I shrank from the idea that except for the poor primitive man torn to pieces in the last painting, mine was the only human form amidst the many relics and symbols of primordial life.
