Arnon (or Arno)
was a regular canon, who followed the rule of his order at Reicherspergh, in Bavaria, where he was dean of that community. He died in 1175, having written against Folmarus, provost of Triefenstein, in Franconia, on the subject of the holy eucharist. His work is in the Bibl. Patrum (Cologne ed.), tom. 13, and in the Auctuarium of Le Mire. He also wrote, Scutum Canonicorusm, in the Miscellanea of Duelli (Augsburg, 1723), vol. i, the design of which was to bring back the brethren of his order to live in its true spirit. This work is interesting, as showing the manner of life, customs, and observances of the regular canons at that period.-Landon, Eccles. Dict. s.v.
