Note: Mythology just means the set of stories involved in a religion. It does not mean anything as to whether these stories are true or false
Much of modern day christian folklore is not found in the bible. Just like how there are many books detailing greco-roman myths beyond what is found in the homeric epics, are there any books detailing the same for christian mythology? Stuff like the circles of hell, the harrowing of hell, the wandering jew, the holy grail, the shroud of turin, the holy prepuce, the stories of the various saints, etc.
I’m not sure if all of it could be covered in a single book, but it seems plausible most of it could be covered in 300 to 400 pages as a general overview.
