What is "disibod"

Saint Disibod (619–700) was an Irish monk and hermit, first mentioned in a martyrologium by Hrabanus Maurus (9th century). Hildegard of Bingen around 1170 composed a vita of Saint Disibod

According to Hildegard's vita, Disibod came to the Frankish Empire in 640 as a missionary, accompanied by his disciples Giswald, Clemens and Sallust. They were active in the Vosges and Ardennes, until, guided by a dream, Disibod built a cell at the confluence of the rivers Nahe and Glan, the location of the later monastery of Disibodenberg.
