'Yeah, I know about this,' Jack said, but Artan could not be stopped: there were piles of silver lying on the ground in Porto Belo, he insisted – consequently its value, compared to that of gold, was plunging – so in Spain (where they used silver money) there was inflation, because it was not worth as much as it had been, whereas in France all gold coins were being hoarded, because gold was expected to be worth more in the future. So now Monsieur Esphahnian had lots of rapidly depreciating silver. He should have sailed to the Levant where silver was always in demand, but he didn't. Instead he sailed for Amsterdam expecting to make some kind of unspecified, brilliant commodities deal that would more than recoup his exchange-rate losses. But (as luck would have it) his ship ran aground, and he got his nuts caught in the mangle of the Thirty Years' War. Sweden happened to be just in the act of conquering Holland when Monsieur Esphahnian's ship eased up onto the sandbank and stopped moving; and, to make a long story short, the Esphahnian dynastic fortune was last seen northbound, strapped to the ass of a Swedish pack-horse.
