Arno of Salzburg

Arno, Arn or Aquila (c. 750–821) was bishop of Salzburg, and afterwards its first archbishop. He preserved his voluminous correspondence from the scholar Alcuin of York.

He entered the church at an early age, and after passing some time at Weihenstephan Abbey, Freising, became abbot of Elnon, or Saint-Amand Abbey as it was afterwards called, where he made the acquaintance of Alcuin.

In 785 he was made bishop of Salzburg and in 787 was employed by Tassilo III, duke of the Bavarians, as an envoy to Charlemagne at Rome. He appears to have attracted the notice of the Frankish king, through whose influence in 798 Salzburg was made the seat of an archbishopric; and Arno, as the first holder of this office, became metropolitan of Bavaria and received the pallium from Pope Leo III.

The area of his authority was extended to the east by the conquests of Charlemagne over the Avars for the Carolingian Empire, and he began to take a prominent part in the government of Bavaria. He acted as one of the missi dominici, and spent some time at the court of Charlemagne, where he was known by the assembled scholars as Aquila, the "Eagle". His name appears as one of the signatories to the emperor's will. He established a library at Salzburg, furthered in other ways the interests of learning, and presided over several synods called to improve the condition of the church in Bavaria.
