Dysibod (Disibod, or Disen), an Irish prelate, was born in Ireland, and was ordained a priest at the age of thirty. He was some time afterwards made bishop, some say of Dublin. When he had governed his see ten years he was compelled to resign it, in 675. He then left Ireland, and travelled into Germany, going from place to place preaching the Gospel, for ten years. At last he arrived at a high, woody mountain, where he settled. He drew many of the order of St. Benedict to him, and founded a monastery on this mountain, which was called Mount Disibod, since changed into Dissenberg. He died there, July 8, in the eighty-first year of his age. His life was written by the abbess Hildegardis. See D'Alton, Memoirs of the Abbs. of Dublin, page 20.
