The Summoning of Everyman, usually referred to simply as Everyman, is a late 15th-century morality play. Like John Bunyan's 1678 Christian novel The Pilgrim's Progress, Everyman uses allegorical characters to examine the question of Christian salvation and what Man must do to attain it.
It's a classic and is referred to in the Logos & Noet descriptions of the Works of Prudentius: "Prudentius’ most significant literary contribution, however, is Psychomachia, which is considered the first major work of pure Christian allegory. The tale of virtue versus vice paved the way for works of medieval allegorical literature like The Divine Comedy, Piers Plowman, Everyman, and even Pilgrim’s Progress."
We have Prudentius's works and The Divine Comedy and Pilgrim's Progress. Piers Plowman (which I've requested elsewhere) and Everyman are nearly on the level with those, and should be available in Logos as well.
