Morality Plays are a genre of medieval and early Tudor theatrical entertainment. They were allegorical dramas that personified moral qualities (such as virtues and vices) or abstractions (such as death or youth) and taught moral lessons. Let's briefly examine each of the options:
The Castell of Perseverance: This is a well-known morality play written around 1425. It allegorizes the struggle of the human soul and portrays virtues and vices.
Mind, Will and Understanding: This is another morality play, written in the mid-15th century. It focuses on the internal struggle between different faculties of the human soul.
Mankind: This is a classic morality play from the late 15th century. It allegorizes the conflict between good and evil influences on Mankind.
The City Heiress: This play, written by Aphra Behn and first performed in 1682, is a Restoration comedy. Unlike the other options, it does not belong to the genre of morality plays but rather to the genre of Restoration comedy, which is characterized by its satirical take on manners and societal norms of the time.
