Awestruck at this unexpected glimpse into a past beyond the conception of the most daring anthropologist, I stood musing whilst the moon cast queer reflections on the silent channel before me. Then suddenly I saw it. With only a slight churning to mark its rise to the surface, the thing slid into view above the dark waters. Vast, Polyphemus-like, and loathsome, it darted like a stupendous monster of nightmares to the monolith, about which it flung its gigantic scaly arms, the while it bowed its hideous head and gave vent to certain measured sounds. I think I went mad then.
