Codex Washingtonianus (the Freer Gospels)

One hundred and eighty-seven leaves, in the order Matthew, John, Luke, Mark. After Mark 16:14 this manuscript alone carries an extra passage, known as the Freer Logion, in which Christ answers the disciples: "The term of years for Satan's power has been fulfilled, but other terrible things draw near." No printed Bible carries it. It is a real variant in a real manuscript, and this room shows it rather than hiding it. Its text also changes character from book to book, which scholars read as evidence that it was assembled from several different damaged copies — plausibly because Diocletian's persecution had destroyed the complete ones. If that reading is right, the book is physical evidence of a church rebuilding its Scriptures after an attempt to burn them.
