Looking up at vast rooves had been Jack’s way to relieve his eyes and mind from the strain of following the action on the ground. There were Eastern men in felt hats with giant rims of rich gleaming fur, talking to long-bearded Jews about racks of animal pelts-the faces of small nasty critters gaping blankly at the sky. Chinese carrying crates of what he had to assume was China, coopers repairing busted casks, bakers hawking loaves, blonde maidens with piles of oranges, musicians everywhere, grinding hurdy-gurdys or plucking at mutant lutes with huge cantilevers projecting asymmetrically from their necks to support thumping bass halyards. Armenian coffee-sellers carrying bright steaming copper and brass tanks on their persons, bored guards with pikes or halberds, turbaned Turks attempting to buy back strange goods that (Jack realized with a shock) had also been looted from the Vienna siege-camp-he was amused but, actually, embarrassed and irritated that others had had the same idea. A hookah-smoking area where Turkish boys in pointy-toed slippers scurried from one small table to the next carrying smouldering braziers of ornately wrought silver from which they selected individual coals with silver tongs and placed them carefully atop the hookahs’ tobacco-bowls to keep them burning. Everywhere, goods: but here in the square they were in casks, or wrapped up in square bales held together by rope-nets, all marked with curious initials and monograms: trade-marks of diverse merchants.

They’d found a place to stable Turk, then gone down a street, worked up their courage, and entered into one of those broad vaulted portals-wide and high enough for three or four horsemen to ride abreast-and entered the courtyard of one of those buildings. This yard was only some ten by twenty paces, and hemmed in on all sides by the four-story-high walls of the building, which were painted a merry yellow so that what sun did enter the yard cast a symbolic golden radiance on all. The court itself was stuffed with people displaying spices, metal goods, jewels, books, fabric, wine, wax, dried fish, hats, boots, gloves, weapons, and porcelain, frequently standing cheek-to-cheek and talking directly into each other’s ears. One whole side of the courtyard, then, gave way to a line of open-sided vaults: an arcade a couple of steps above courtyard level, separated from the courtyard only by a row of stout pillars, and tucked in underneath the actual house. In each vault a grave man in good clothes sat at a mighty desk, or banca, with several immense Books, strapped, buckled, and padlocked shut when not in use; an inkwell; quills; and on the floor next to him, a black chest all wrapped about with bronze or iron straps, hinges, chains, and locks of a weight and quality normally seen on arsenal-gates. Sometimes bales and casks of goods were mounded up next to him. More often, the stuff was piled out in the courtyard. Sixty or eighty feet above, stout beams projected from the tops of dormers, thrusting pulleys out over the yard, and by means of ropes through those pulleys, laborers hoisted the goods up for storage in the cavernous attics.

“They are betting prices will rise,” Eliza said, observing this, and this was the first inkling Jack received that this was more than a country swap-meet, and that there were layers of cleverness at work here that went far beyond simply knowing how many thalers should buy a tub of butter.

Jack saw so much that was strange in Leipzig, and saw it so fast, that he had to put most of it out of his mind immediately to make room for new material, and didn’t remember it until later, when taking a piss or trying to go to sleep, and when he did remember it, it seemed so strange to him that he couldn’t be sure whether it was a dream, or something that had really happened, or proof that the mines that the French Pox had (he suspected) been patiently excavating under his brain for the last several years, had finally begun to detonate.

There had been, for example, a trip inside one of the factories*to exchange some odd coins that Jack had picked up along his travels and been unable to spend, as no one recognized them. In this room, men sat behind desks with books in whose pages were circular cut-outs made to hold coins-two of each coin, so both heads and tails could be viewed in the same glance, and each coin labeled with various cryptic numbers and symbols in different colors of ink. The money-changer paged steadily through this book until he found a page holding coins just like Jack’s, though crisper and shinier. He took out a f?ry-sized scale made out of gold, whose pans, no larger than dollars, were suspended from its fragile cross-bar by blue silken cords. He put Jack’s coins on one pan and then, using tweezers, piled featherweight scraps of marked gold foil on the other pan until they balanced. Then he put the scale back into its wooden carrying-case, which was smaller than Eliza’s hand; did some calculations; and offered Jack a couple of Leipziger Ratsmarken (Leipzig minted its own coins). Eliza insisted they visit a couple of other money-changers and repeat the ceremony, but the results were always the same. So finally they accepted the Leipziger coins and then watched the money-changer fling Jack’s old coins into a box in the corner, half full of assorted coins and fragments of jewelry, mostly black from tarnish. “We’ll melt it down,” he explained when he saw the look on Jack’s face. Eliza, meanwhile, was staring at a wall-chart of exchange rates, reading the names of the coins that had been chalked up there: “Louis d’or, Maximilian d’or, souverain d’or, rand, ducat, Louis franc, Breslau ducat, Schildgroschen, Hohlheller, Schwertgroschen, Oberwehr groschen, Hellengroschen, pfennig, Goldgulden, halberspitzgroschen, Engelsgroschen, Real, Ratswertmark, 2Z3 thaler, English shilling, ruble, abassid, rupiah…”

“Just goes to prove we have to get into the money-making business,” Jack said when they left.

“To me it proves that the business is crowded and hard-fought,” Eliza said. “Better to get into silver-mining. All the coiners must buy from miners.”

“But Herr Geidel would rather have burning splints under his nails than own another silver mine,” Jack reminded her.

“It would seem to me better to buy into something when it is cheap, and wait for it to become dear,” Eliza said. “Think of those trading-houses with their attics.”

“We don’t have an attic.”

“I meant it as a figure of speech.”

“So did I. We have no way to purchase a silver mine and sew it into your skirts and carry it round until the price goes up.” This sounded to Jack like a sure-fire conversation ender but only produced a thoughtful expression on Eliza’s face.

Consequently they found themselves at the Bourse, a small tidy rectangular building of white stone packed with well-dressed men screaming at each other in all the languages of Christendom but bound together by some Pentecostal faith in the Holy Spirit of the Messe that made all tongues one. There were no goods in evidence, only bits of paper, which was so odd that Jack would’ve stayed up all night wondering over it if he hadn’t forgotten immediately in light of later developments. After a brief conversation with a trader who was taking a breather on the edge of the floor, smoking a clay-pipe and quaffing some of that fine golden beer from Pilsen, Eliza returned to Jack with a triumphant and determined look about her that boded ill. “The word is Kuxen, ” she said, “we wish to buy Kuxen in a silver mine.”

“We do?”

“Isn’t that what we just decided?” She was joking, perhaps.

“First tell me what Kuxen are.”

“Shares. The mine is divided in half. Each half into quarters. Each quarter into eighths, and so on-until the number of shares is something like sixty-four or one twenty-eight-that number of shares is then sold. Each share is called a kux. ”
