Adalar

Holy Hieromartyr Adalar, also called Adolar or Aethelheri, was one of the companions of Saint Boniface and, according to tradition, bishop of Erfurt. He was killed by pagan Frisians near Dokkum in Frisia on 5 June 754 (or 755), together with Boniface and many other companions, among them Saint Eoban.

His relics, with those of Eoban, were taken after 756 from Utrecht to the abbey of Fulda and buried beside those of Boniface. Before 1100 they were moved to Erfurt, where they were found in 1154. His tomb is still in the cathedral of Erfurt. According to a legend he was the first and only bishop of the diocese of Erfurt, founded by Boniface in 742 (741 by other sources), which was joined to the diocese of Mainz after his death. He is shown in priestly vestments with a book, sometimes in bishop's vestments. He is patron of the city of Erfurt and of cattle; the chapel of St. Adolari at the Pillersee is dedicated to him. He is honored as a saint of the undivided Church.
