"Simply Literal" Scripture Interpretation Long Before The Reformation

Critics of Protestantism often make much of the large amount of allegorizing in the church fathers' interpretations of scripture. But there was a lot of diversity in how scripture was interpreted, including interpretive approaches of a more literal nature, long before the Reformation. Though Jerome allegorized a lot, he acknowledged that other people in his day didn't:

"In the Scriptures, the words are not simply literal, as some think." (in Thomas Scheck, trans., St. Jerome: Commentary On Isaiah [Mahwah, New Jersey: The Newman Press, 2015], p. 938, Letter 18A:12)

You often come across comments like those in pre-Reformation sources. Whether they name who they have in mind or not, they refer to a diversity of interpretive methods and interpretations. Even among those who allegorized a lot, there was a lot of variation in terms of how they did so, the extent to which they did it, etc. There's diversity among those who interpret scripture more literally as well.
