Saint Fridolin

Fridolin of Säckingen, also known as Fridold or Fredelinus, was an Irish missionary and apostle to the Alamanni who founded Säckingen Abbey on the Upper Rhine. He is celebrated for his role in spreading Christianity among the Alamanni tribes and is venerated as a saint by the Church. His feast day is observed on March 6th. According to later tradition, his mission began during the reign of Clovis I (r. 509–511) and he died during the reign of Theudebert I (r. 533–548), with a traditional date of death being March 6, 538 or 540. However, modern historiography tends to place his life in the 7th century under Clovis II (r. 639–657). He is particularly noted for his connection to Glarus, where he is considered a patron saint.
