As part of my ongoing one-man-battle against medieval bias, I want to point out the significance of the mystery and morality play cycles.
It was often alleged, in Enlightenment times and later, that the medieval person was superstitious, uneducated, and that the clergy wanted to keep the Bible away from Catholics in order to subjugate them. Nothing could be further from the truth.
Keep in mind the mystery and morality plays came into existence prior to the invention of the printing press. People did not have access to Bibles and books, and so public education typically took place through the play cycles and public oratory which would cover almost every aspect of the Old and New Testaments. Medieval people were, in fact, remarkably familiar with the stories of the Bible, and received a moral education through these plays, which were considered to provide a great service to the populace.
Cycles typically ran between 30 and 50 plays per annual cycle depending on the regional cathedral (Wakefield was 32 plays). This covered a huge amount of material!
The Wakefield cycles took place mainly in the courtyard and square of Wakefield Cathedral, pictured below (Actors and orators would often stand on the steps to be elevated above the crowds):
