The fifteenth-century manuscript Wissenschaftliche Stadtbibliothek Mainz, Hs I 109, from the Carthusians of Mainz, consists of four parts. A sixteenth-century addendum at the end of part 3 (fol. 109v) includes a list of around 20 books. The first two items from the list belong to the third part of the manuscript, but the rest do not.
The final line of the list begins: Item Reuelacioes methodij
The library's manuscript catalog doesn't mention Methodius, but does describe the rest of the works as "primarily theological, grammatical and medical writings, including Sebastian Brant's Narrenschiff, Jakob Wimpfeling's Elegantiarum medulla and Isidoneus Germanicus, Johannes Marius Philelphus' Novum epistolarium." (I also see Johannes de Sacrobosco's De sphaera mundi in the book list.)
It's always interesting to get another data point on who owned prophecies, and in what context.
