Arbeo of Freising was an early medieval bishop and author who served the diocese of Freising starting in 764. Born near Merano around 723, he belonged to the Huosi noble family and joined the Benedictine Order. After serving as a priest and notary, he became the abbot of Scharnitz before succeeding Joseph as bishop. Throughout his career, he supported King Charlemagne during political conflicts involving the Bavarian dukes and played a significant role in establishing several Bavarian monasteries.
