Indexing notes: 
The text of this incipit is difficult to read, but appears to be "Rorate celi, which occurs throughout Advent (in this manuscript) with the hymn "Conditor". The indexer suggested instead "Nox praecessit", but there is only one other instance of "Nox praecessit" as a versicle in Cantus: H-Bu lat 118, 126v.
