Part 3

This mirror--according to popular tales a trophy as potent in its way as the better-known Aegis of Minerva or Hammer of Thor--was a small oval object called "Loki's Glass," made of some polished fusible mineral and having magical properties which included the divination of the immediate future and the power to show the possessor his enemies. That it had deeper potential properties, realizable in the hands of an erudite magician, none of the common people doubted; and even educated persons attached much fearful importance to Holm's rumored attempts to incorporate it in a larger glass of immortality. Then had come the wizard's disappearance in 1687, and the final sale and dispersal of his goods amidst a growing cloud of fantastic legendry. It was, altogether, just such a story as one would laugh at if possessed of no particular key; yet to me, remembering those dream messages and having Robert Grandison's corroboration before me, it formed a positive confirmation of all the bewildering marvels that had been unfolded.

But as I have said, there is still another line of rather positive evidence--of a very different character--at my disposal. Two days after his release, as Robert, greatly improved in strength and appearance, was placing a log on my living-room fire, I noticed a certain awkwardness in his motions and was struck by a persistent idea. Summoning him to my desk I suddenly asked him to pick up an ink-stand--and was scarcely surprised to note that, despite lifelong right-handedness, he obeyed unconsciously with his left hand. Without alarming him, I then asked that he unbutton his coat and let me listen to his cardiac action. What I found upon placing my ear to his chest--and what I did not tell him for some time afterward--was that _his heart was beating on his right side_.

He had gone into the glass right-handed and with all organs in their normal positions. Now he was left-handed and with organs reversed, and would doubtless continue so for the rest of his life. Clearly, the dimensional transition had been no illusion--for this physical change was tangible and unmistakable. Had there been a natural exit from the glass, Robert would probably have undergone a thorough re-reversal and emerged in perfect normality--as indeed the color-scheme of his body and clothing did emerge. The forcible nature of his release, however, undoubtedly set something awry; so that dimensions no longer had a chance to right themselves as chromatic wave-frequencies still did.

I had not merely _opened_ Holm's trap; I had _destroyed_ it; and at the particular stage of destruction marked by Robert's escape some of the reversing properties had perished. It is significant that in escaping Robert had felt no pain comparable to that experienced in entering. Had the destruction been still more sudden, I shiver to think of the monstrosities of color the boy would always have been forced to bear. I may add that after discovering Robert's reversal I examined the rumpled and discarded clothing he had worn in the glass, and found, as I had expected, a complete reversal of pockets, buttons, and all other corresponding details.

At this moment Loki's Glass, just as it fell on my Bokhara rug from the now patched and harmless mirror, weighs down a sheaf of papers on my writing-table here in St. Thomas, venerable capital of the Danish West Indies--now the American Virgin Islands. Various collectors of old Sandwich glass have mistaken it for an odd bit of that early American product--but I privately realize that my paper-weight is an antique of far subtler and more paleologean craftsmanship. Still, I do not disillusion such enthusiasts.
