Bunyan’s allegories (e.g., Pilgrim, Holy War) have been so iconic and profitable to the Church for the past 350 years that I think it would be useful to any teacher or preacher to have Logos develop interactive media that not only summarizes the content but also aids in locating and citing the content. Events, locations, names of friends of the gospel, names of the enemies of the gospel, dialogues, scripture references and allusions, etc.
