The Sankt Florian Psalter or Saint Florian Psalter (Latin: Psalterium florianense or Psalterium trilingue, German: Florianer Psalter or Florianspsalter, Polish: Psałterz floriański or Psałterz św. Jadwigi) is a brightly illuminated trilingual manuscript psalter, written between late 14th and early 15th centuries in Latin, Polish and German. The Polish text is the oldest known translation of the Book of Psalms into that language. Its author, first owners, and place of origin are still not certain. It was named after St. Florian Monastery in Sankt Florian, a town in Austria, where it was discovered.
