AOI

Certain lines of the Oxford manuscript end with the letters "AOI". The meaning of this word or annotation is unclear. Many scholars have hypothesized that the marking may have played a role in public performances of the text, such as indicating a place where a jongleur would change the tempo. Contrarily, Nathan Love believes that "AOI" marks locations where the scribe or copyist is signaling that he has deviated from the primary manuscript: ergo, the mark indicates the source is a non-performance manuscript.
