Landelinus of Ettenheimmünster

Landelinus of Ettenheimmünster was an Irish monk and hermit who came to the Ortenau in south-⁠western Germany at the beginning of the seventh century. He is venerated as a saint in the Western Church.

According to tradition, he was one of the first Christian missionaries of the region and was killed by pagan hunters. Five springs are said to have gushed forth where he was slain. He is thought to have reposed around 640.

Near his grave a small community of monks grew up over time, which Bishop Widegern of Strasbourg organized around 728 as a "cell of monks". His successor, Bishop Etto, confirmed the foundation, bound the monks to the Rule of Saint Benedict and around 763 had a new monastery built at Ettenheimmünster, where the saint had lived as a hermit.

A local cult of the saint is attested in the diocese of Strasbourg from the eleventh century. He is invoked for diseases of the eyes, and pilgrims still bathe their eyes with the water of the spring named after him. His feast is 21 September (22 September in the Archdiocese of Freiburg). In the mounted procession of the patronal feast a silver reliquary of 1506, in the form of a bust of the saint, is carried; it is kept in the pilgrimage church at Ettenheimmünster.
