I do not know. If that abyss and what I held were real, there is no hope. Then, all too truly, there lies upon this world of man a mocking and incredible shadow out of time. But, mercifully, there is no proof that these things are other than fresh phases of my myth-born dreams. I did not bring back the metal case that would have been a proof, and so far those subterrene corridors have not been found.
If the laws of the universe are kind, they will never be found. But I must tell my son what I saw or thought I saw, and let him use his judgment as a psychologist in gauging the reality of my experience, and communicating this account to others.
I have said that the awful truth behind my tortured years of dreaming hinges absolutely upon the actuality of what I thought I saw in those Cyclopean, buried ruins. It has been hard for me, literally, to set down that crucial revelation, though no reader can have failed to guess it. Of course, it lay in that book within the metal case – the case which I pried out of its lair amidst the dust of a million centuries.
No eye had seen, no hand had touched that book since the advent of man to this planet. And yet, when I flashed my torch upon it in that frightful abyss, I saw that the queerly pigmented letters on the brittle, aeon-browned cellulose pages were not indeed any nameless hieroglyphs of earth's youth. They were, instead, the letters of our familiar alphabet, spelling out the words of the English language in my own handwriting.
