What was a pageant cart? Why were those so important in the Medieval era, and how do they influence theatre today?

A pageant wagon is a movable stage or wagon used to accommodate the mystery and miracle play cycles of the 10th through the 16th century. These religious plays were developed from biblical texts; at the height of their popularity, they were allowed to stay within the churches, and special stages were erected for them.

Pageant comes from the archaic word for the wagon stage, "pagyn." It is a word used to describe the movable stage on which a scene of the processional religious play was performed.

The origin of the religious play began in medieval churches. The dramas began as a simple way to impart the message of the Bible to the people.
