Saint Colman was a 7th-century Irish priest and missionary who traveled to central Europe to spread Christianity. Alongside his companions Kilian and Totnan, he conducted missionary work throughout the regions of Franconia and Thuringia. After visiting Pope Conon in Rome, the group settled in Würzburg. His life ended abruptly when he and his fellow missionaries were executed in the town square following a dispute involving the local ruler, Duke Gozbert, and his wife.
