Baring-Gould’s sources: Mentioned in the German Martyrologies. His life was written by a monk of Prufening, about the year 1290.

S. Erminold sprang from one of the first families in Swabia, and was given in early life to William, abbot of Hirschau, to be educated. A better tutor could not have been found for him, for William was one of the most learned and pious men of the age. The youthful Erminold made rapid progress in his studies, and he grew up in favour with God and man. When his pupilage was ended, he took the vows of monastic life upon him. In 1110, he was appointed by the Emperor Henry V., to the abbey of Lorch, on the Rhine; but hearing that this had been given him at the request of his brother, as a return for something his brother had done for the Emperor, Erminold threw up the office, so as not to incur the least suspicion of simony, and returned to Hirschau. But the Bishop of Bamberg, having founded an abbey at Prufening, near Ratisbon [Regensburg in Bavaria], he was invited to colonize it, and be its first father. He accordingly betook himself thither, with a few brethren. Having incurred the hostility of some of his monks, by insisting on strict discipline, one, named Aaron, struck him with a knife and mortally wounded him. He died, forgiving his murderer.
