Jack had tied a strip of cloth over his eyes so that he could lie in the sun comfortably, and had unrolled a straw mat on the stones of the courtyard to even out the bumps somewhat, but except for a few negligible layers of skin, hair, and straw, his skull was in direct contact with the stones. Even if he stopped up his ears with his fingers, blocking out the noises of living things, certain vibrations of a mineral nature were still conducted into his head through that route, and even when no carts happened to be passing by, Jack fancied he could sense the omnipresent grumble of those grinding-stones, thousands of granite molars chewing the maize and cacao of this country. Which might be mistaken as the deepest ground-note, the continuo-line of this neverending Mass that was Mexico City. Except that there was another note even more pervasive. Jack did not hear it for a while, or if he did he could not disentangle it from the city’s other noises. But after he had been lying there for some time he went half to sleep and had some strange vision that, if he’d been a Papist, probably would have been accounted a miracle and got him nominated a Saint. The vision was that his body was a body of light, rising up and growing as it rose, as bubbles do when they come up out of a black depth, but that it was bound with thongs of darkness, somewhat as the light of a lanthorn appears to be gibbeted by the straps of iron that clasp it all round. At any rate, something about this sun-intoxicated state of mind, and the general drugged stupor that followed a torture-session, caused the brocade of sounds to unravel itself and come apart into its several threads, yarns, warps, and woofs. And in this way Jack became aware of the sound of the Mint.
