The sight between the bulwarks was far more lovely and surprising than the spectacle presented by the ship's sides. For the decks seemed not only formed of shells of a hundred different hues; there was a great abundance of branching corals, white as milk, and marine plants of kinds for which I could not find names, of several brilliant colours; so that, what with the delicate velvet of the moss, the dark shades of seaweed of figurations as dainty as those of ferns, and the different sorts of shells, big and little, all lying as solid as if they had been set in concrete, the appearance of the ship submitted was something incredibly fantastic and admirable. Whether the hatches were on or not I could not tell, so thickly coated were the decks; but whether or not, the deposits and marine growths rendered the surface as impenetrable as iron, and I believe it would have kept a small army of labourers plying their pickaxes for a whole week to have made openings into the hold through that shelly coating of mail. My eye was taken by a peculiar sort of protuberance at the foot of the mainmast. It stood as high as I did, and had something of the shape of a man, and, indeed, after staring at it for some time, I perceived that it had been a man; that is to say, it was a human skeleton, filled up to the bulk of a living being by the shells and barnacles which covered it. Ashore, it might have passed for some odd imitation in shells of the human figure; but, viewing it as I did, in the midst of that great ocean, amid the frightful solitude of the great dome of heaven, in a ship that was like the handiwork of the sea-gods at the bottom of the deep--I say, looking at it as I did, and knowing the thing had had life in centuries past, and had risen thus wildly garnished out of the unfathomable secret heart of the ocean, it awed me to an extent I cannot express, and I gazed as though fascinated. In all probability, this was a man who, when the ship foundered, had been securely lashed to the mast for safety or for punishment. I turned away at last with a shudder, and walked aft. The wreck was unquestionably some Spanish or Portuguese carrack or galleon as old as I have stated; for you saw her shape when you stood on her deck, and her castellated stern rising into a tower from her poop and poop-royal, as it was called, proved her age as convincingly as if the date of her launch had been scored upon her.
