Adalarius (Athalarius, or Adelherius)

Adalarius (Athalarius, Or Adelherius), a priest who accompanied St. Boniface to Frisia in 754 and shared with him the glory of martyrdom. His body was translated from Utrecht to Erfurt with that of St. Eoban, and buried in the Monastery of St. Mary. In the Breviary of Erfurt he is commemorated with a double rite, April 20, as episcopus et martyr. It is supposed that the title of bishop was a baseless assumption, but probably gave rise to Baillet's statement, which rests apparently on no historical foundation, that Adalarilus was the first and only bishop of Erfurt. the see after his death being united to that of Mentz.
