In all parts of this kingdom of Peru we who have travelled over it know that there are great fairs or markets, where the natives make their bargains. Among these the greatest and richest was formerly in the city of Cuzco, for even in the time of the Spaniards its greatness was caused by the gold which was bought and sold there, and by the other things of all kinds that were sent into the city. But this market or fair at Cuzco did not equal the superb one at Potosi, where the traffic was so great that, among the Indians alone, without including Christians, twenty-five or thirty thousand golden pesos exchanged hands daily. This is wonderful, and I believe that no fair in the world can be compared to it. I saw this fair several times, and it is held in a plain near the town. In one place there were cestos (bags) of coca, the most valuable product in these parts. In another place there were bales of cloth and fine rich shirtings. Here were heaps of maize, dried potatoes, and other provisions, there great quantities of the best meat in the country.
