Astolfus of Mainz

Astolfus of Mainz (Haistulph, Atulf, Astolphe) was archbishop of Mainz from 813 or 814 until his death on 28 December 825. He is venerated as a saint in the Western Church and commemorated on 5 January.

He seems to have been of Lombard origin and was a pupil of Lul, his predecessor's predecessor. He was elected to succeed Archbishop Richulf, his uncle, and held the see of Mainz in 814, since on 23 December of that year he ordained Hrabanus Maurus, the monk of Fulda, who would later succeed him. His relations with the abbey of Fulda and its abbots were close. Hrabanus dedicated to him the work De institutione clericorum and his commentaries on Matthew. Delighted with the learning and clarity of speech of the author, the archbishop charged him with composing homilies on the Scripture texts that were customarily explained to the people.

He was buried in the church of the abbey of Saint Alban before Mainz.
