The Wachtendonck Psalms are a collection of Latin psalms, with a translation in an eastern variety of Old Dutch. It contains a number of Old High German elements, because it was probably based on a Middle Franconian original. Very little remains of them. The psalms were named after a manuscript which has not come down to us, but out of which scholars believe the surviving fragments must have been copied. This manuscript was once owned by Liège Canon Arnold Wachtendonck. He was supervisor over Munsterbilzen Abbey, where he found the manuscript.
