The malpais. It was a maze. Ye’d run out upon a little promontory and ye’d be balked about by the steep crevasses, you wouldnt dare to jump them. Sharp black glass the edges and sharp the flinty rocks below. We led the horses with every care and still they were bleedin about their hooves. Our boots was cut to pieces. Clamberin over those old caved and rimpled plates you could see well enough how things had gone in that place, rocks melted and set up all wrinkled like a pudding, the earth stove through to the molten core of her. Where for aught any man knows lies the locality of hell. For the earth is a globe in the void and truth there’s no up nor down to it and there’s men in this company besides myself seen little cloven hoof-prints in the stone clever as a little doe in her going but what little doe ever trod melted rock? I’d not go behind scripture but it may be that there has been sinners so notorious evil that the fires coughed em up again and I could well see in the long ago how it was little devils with their pitchforks had traversed that fiery vomit for to salvage back those souls that had by misadventure been spewed up from their damnation onto the outer shelves of the world. Aye. It’s a notion, no more. But someplace in the scheme of things this world must touch the other. And somethin put them little hooflet markings in the lava flow for I seen them there myself.
From Cormac McCarthy’s novel Blood Meridian.
