The Bible is 66 books, but those books aren’t just thrown together willy-nilly. They’re grouped by type: Law, History, Poetry and Wisdom, Prophets, Gospels, Letters and more. Here’s the 40,000-foot view of who traditionally wrote them, where they fit in the biblical timeline, and what each one is about.
Note: Where authorship isn’t certain, I’ve either listed it as unknown or noted the traditional attribution. Because we are not making stuff up in the Bibliotheca.
