Just when my fancy merged into real sight I cannot tell; but there came a gradual glow ahead, and all at once I knew that I saw the dim outlines of the corridor and the cases, revealed by some unknown subterranean phosphorescence. For a little while all was exactly as I had imagined it, since the glow was very faint; but as I mechanically kept stumbling ahead into the stronger light I realized that my fancy had been but feeble. This hall was no relic of crudity like the temples in the city above, but a monument of the most magnificent and exotic art. Rich, vivid, and daringly fantastic designs and pictures formed a continuous scheme of mural painting whose lines and colors were beyond description. The cases were of a strange golden wood, with fronts of exquisite glass, and containing the mummified forms of creatures outreaching in grotesqueness the most chaotic dreams of man.
