'He Advanced Him 200 Lambs of Gold': The Pamiers Manuscript - A Fair Was Serious Business

To us, fairs are pretty much just amusements. But in Europe during the Middle Ages and Renaissance, they were serious business affairs— the major engines of economic growth.

Most towns had had a market day since ancient times— a certain day of the week set aside for buying and selling produce and other goods. But in the 1100s, the most ambitious cities in Europe began to host annual international trade fairs lasting one to three weeks, often coinciding with holy days and pilgrimages. These fairs drew buyers and sellers— in both cases mostly merchants and middlemen— from much greater distances than a market day: at a single fair, merchants from Italy, France, and the Low Countries might be found selling their wares. The most important commodities were fabrics. They ranged from coarser cloths of flax or wool to fine woven silks, a specialty of Lyon in southern France. The Lyon Fair was established by Charles VII in 1420, only a few years or so before the Pamiers text was written.

Beginning in the 1100s, the annual fairs held in Provins and five other towns in the Champagne and Brie regions helped circulate textiles, spices, and other fine goods between northern Italy, Catalonia, and southern France, on the one hand, and northern Europe on the other. A fondaco was a combination of an inn, warehouse, and factory. (Image: Provins Office of Tourism.)


These fairs became a central feature of the economy of late Medieval and early Renaissance Europe, driving social development as a whole:

  • To protect the merchants and their stalls of goods that were set up in the streets, rulers organized forces of fair wardens with the power to arrest and try wrongdoers, and these evolved into the police forces and courts of European cities.
  • Special “King’s Roads” were built to convey merchants and merchandise safely and efficiently to the host cities, and these became the major thoroughfares of the region.
  • Lodgings for out-of-town buyers and sellers, and storehouses for their wares, evolved into hostelries, warehouses, and factories.
  • Merchants arriving from other countries hired advocates to argue for their interests, and these developed into foreign consulates.
  • Cities and governments grew bigger and wealthier by hosting fairs and then levying entry and exit tolls, sales taxes, and fees for weighings and measurings.
  • Loans, credit purchases, and “bills and letters of exchange” were invented so that merchants could raise the capital needed to pay craftsmen for their feverish work during the months leading up to a fair.
  • Exchange between foreign currencies at major fairs became so important that it sparked the ascendance of banking and finance over trade and manufacturing.

In the following problem, two merchants arriving at a fair with some raw wool are charged a duty, or import tax, at some set rate that we aren’t told. The collected duties would be forwarded to the local or national government, helping to enrich them.

Problem 7. Two merchants went to the fair; the first had 20 sacks of wool, for which he paid the duty collector 1 sack of the wool, and the collector returned to him 2 liras; the second had 60 sacks of wool, for which he paid the collector 2 sacks of wool plus 6 liras. I ask the value of each sack of the wool, and how much was paid the collector per sack. (Sesiano 1984, p. 56)

Note that the duties, and any “change” returned, could be paid either with liras or with wool itself. There are two unknowns that are requested, which can be found from the two linear relationships that are involved.

Solutions to Problem 7 by double false position and by algebra

Fibonacci’s Liber Abbaci, mentioned earlier, included three consecutive maritime import problems very similar to the fair problem above. Instead of duties on wool in liras, these involve, respectively, freight charges on wool in soldi, customs on precious stones in bezants, and customs on fish in denari (see Sigler 2002, pp. 395-397).

The poor fellow in the next problem is a disgrace to the merchandising profession, since he is spending money almost as fast as he is earning it!

Problem 8. A man entered a fair, and the first day doubled all his money and spent 1 gros; likewise on the second tripled all his money that he had left and spent 2 gros; likewise on the third quadrupled his money that he had left and spent 2 gros, and found that he had nothing but 3 gros. I ask how much money he carried [to the fair]. (Sesiano 1984, p. 58)

The author of the manuscript showed how to solve this problem by double false position. Of course, it can also be solved by inversion (“working backward”) or by algebra.
