It is well that the reader accept nothing which follows as objective truth, for since the events transcend natural law, they are necessily the subjective and unreal creations of my overtaxed mind. When I attained the conning tower I found the sea in general far less luminous than I had expected. There was no animal or vegetable phosphorescence about, and the city that sloped down to the river was invisible in blackness. What I did see was not spectacular, not grotesque or terrifying, yet it removed my last vestige of trust in my consciousness. For the door and windows of the undersea temple hewn from the rocky hill were vividly aglow with a flickering radiance, as from a mighty altar-flame far within.

Later incidents are chaotic. As I stared at the uncannily lighted door and windows, I became subject to the most extravagant visions – visions so extravagant that I cannot even relate them. I fancied that I discerned objects in the temple; objects both stationary and moving; and seemed to hear again the unreal chant that had floated to me when first I awaked. And over all rose thoughts and fears which centered in the youth from the sea and the ivory image whose carving was duplicated on the frieze and columns of the temple before me. I thought of poor Kienze, and wondered where his body rested with the image he had carried back into the sea. He had warned me of something, and I had not heeded – but he was a soft-headed Rhinelander who went mad at troubles a Prussian could bear with ease.

The rest is very simple. My impulse to visit and enter the temple has now become an inexplicable and imperious command which ultimately cannot be denied. My own German will no longer controls my acts, and volition is henceforward possible only in minor matters.
