Munderic of Arisitum

Saint Munderic of Arisitum, hierarch (also called Mondry or Monderic), was a Frankish bishop of the 6th century, venerated as a saint in the Western Church and remembered on 18 March. Some identify him with Saint Mondry of Cellettes, hence the further dates of 10 and 12 May.

He was first consecrated coadjutor to Bishop Tetricus of Langres, who had suffered a stroke, with the understanding that he would serve as archpriest of Tonnerre until Tetricus died. In the war between the kings Guntram and Sigibert, Munderic gave gifts and supplies to Sigibert, and for this he was sent into exile, held for two years in a small roofless tower on the bank of the Rhône, in great hardship. Metropolitan Nicetius of Lyon intervened for him. After his release he went to Austrasia, to King Sigibert I, who made him bishop of a newly founded see, with fifteen parishes and the village of Arisitum, within the diocese of Bishop Dalmatius of Rodez. The sources give a date for his death around 580, but also later, around 600.
