What is the X in X-mas?
(Dutch: "chamber of rhetoric"), medieval Dutch dramatic society. Modelled after contemporary French dramatic societies (puys), such chambers spread rapidly across the French border into Flanders and Holland in the 15th century. At first they were organized democratically; later they acquired sponsorship by the nobility and had a designated leader, assistants, a paid manager, and a jester. Like guilds, they had their own names, slogans, and emblems and were commissioned by the towns that protected them to provide the ceremonial at local festivals.
