I have been a Christian nigh on 40 years and only today do I read of the way that scrolls were stored with labels. This makes sense in as much as one scroll looks much like another. Labelling the scroll or affixing a label makes sense. These early labels do not form part of the text and so when there was a transition to books it didn't make the transition. Gospels were not published anonymously as we might suppose but were labelled and their authors known. Thucydides and Herodotus did mention their name in the body of the text . Plutarch and Suetonius did not. Anyone know where there is an article explaining this clearly?
