"Personent hodie" was first published in which 1582 songbook?

“Personent hodie” was first published in the 1582 songbook Piae Cantiones. The collection preserved late-medieval Latin songs sung in Finnish cathedral schools, making it an important source for Christmas music with medieval roots.

Piae Cantiones was compiled by Jacobus Finno, also known as Jaakko Suomalainen, and published by Theodoricus Petri Rutha of Nyland. Its 74 songs were printed in Greifswald, in the Duchy of Pomerania, although the repertoire was associated with Finland and Sweden.

The melody is older than the printed book. A closely related version appears in a manuscript from around 1360 in Moosburg, Bavaria. The text may also derive from an earlier song honoring Saint Nicholas. Modern listeners may know the tune through English adaptations, including “Let the Song Be Begun” and “On This Day Earth Shall Ring.”
