Merchants from several countries gather for several weeks at set times each year at an inland town in Champagne to trade cloth, spices and money. What kind of gathering is this, and how does it differ from the town's weekly market?
Explanation
A gathering that runs for weeks, recurs at long intervals and pulls in traders from distant regions deals in wholesale and long-distance business rather than in the daily supply of one locality. The enlarged weekly market fails because that market existed to serve the surrounding countryside with everyday goods, whatever size it reached.
