Severin of Cologne was the bishop of Cologne, venerated as a confessor and miracle-worker. A native of Bordeaux, he was a powerful defender of orthodoxy, staunchly opposing Arianism. Before his episcopal appointment, he experienced a vision: his staff budded and flowered, signaling his divine calling. He founded a monastery dedicated to Saints Cornelius and Cyprian—today Cologne’s Basilica of St. Severinus—and reportedly witnessed the ascent of St. Martin of Tours’ soul into heaven. His bones are enshrined in Cologne, and he is invoked against drought and misfortune.
