'The Clarke Plato': the oldest manuscript (discounting papyrus fragments) for about half the dialogues of Plato, perhaps once the first volume of a two-volume set. Commissioned by Arethas of Patrae (bishop of Caesarea, 902-c. 939), who paid 21 gold coins for the copying and the parchment, and added scholia in the margin in a tiny uncial hand (with at least one other contemporary hand).
