Died 640. Arnulf was a courtier of the Austrasian King Theodebert II, a valiant warrior, and a valued adviser. He married the noble Doda (the marriage of his son Ansegisel to Begga, daughter of Blessed Pepin of Landen, produced the Carolingian line of kings of France).

Arnulf desired to become a monk at Lérins. However, when his wife took the veil and Arnulf was at the point of entering Lérins, he was appointed bishop of Metz about 610. He played a prominent role in affairs of state, was one of those instrumental in making Clotaire of Neustria king of Austrasia, and was chief counselor to Dagobert, son of King Clotaire, when the king appointed him king of Austrasia.

About 626, Arnulf resigned his see and retired to a hermitage near the abbey of Remiremont Delaney, Encyclopedia).

In art, Saint Arnulf is portrayed as a bishop with a coat of mail under his cope. He may also be shown (1) with a fish having a ring in its mouth; (2) blessing a burning castle; or (3) washing the feet of the poor (Roeder). He is venerated at Remiremont. Like Saint Antony, Arnulf is invoked to find lost articles. He is also the patron saint of music, millers, and brewers (Roeder). 2
