I had never heard of Everyman or morality plays before your post. I learned that a morality play was an allegory where the protagonist faced many personified characters to test his faith. I think this is good to preserve because it shows the importance of religion back in the medieval times. It is inspiring to see that religion impacted people's morals of that time greatly. 

Do you know which type of play was more popular at the time? Mystery or morality?
