(died c. 617 [?]) is said to have lived as a hermit in the hill country between the Hunsrück and the Palatine Forest in the time of Bishop Magnerich of Trier (died after 587). The 10th-century calendar of Stavelot Abbey is the earliest evidence of cultic veneration of his grave at the site later named Sankt Wendel; its late Gothic hall church (consecrated in 1360) was built to enshrine his relics. Wendelin has been venerated since the late Middle Ages as the patron saint of herdsmen and cattle.
