Today is the feast day of St. Columbanus of Ghent (543 CE–February 15, 959 CE), not to be confused with Columbanus from three centuries earlier. He was a patron saint of Belgium, Ghent, and brewers. He was probably born in Ireland but moved with his followers to Ghent, Belgium, to escape raiding parties. There isn’t a great deal of information about him, and he’s not much remembered outside Belgium. He’s buried in the cathedral of Ghent, which at the time was known as the church of St. Bavo. His name is in the litany to be recited in Belgium during public emergencies.
This account is from Celtic Saints:
Saint Columbanus was probably an Irish abbot who led his community to Belgium following the constant raids of the Norsemen. On February 2, 957, Columbanus became a hermit in the cemetery near the church of Saint-Bavo at Ghent, where he acquired a wide reputation for holiness. He is buried in the cathedral and is one of the patrons of Belgium.
This one is from Omnium Sanctorum Hiberniae:
February 2 is the commemoration of a tenth-century Irish recluse at Ghent in Belgium. It seems, to judge from the footnotes to Canon O’Hanlon’s entry for Saint Columban, that he has been confused with his more famous namesake, Saint Columban (Columbanus) of Bobbio. It also seems that the saint is commemorated on the day of his enclosure as a hermit, February 2 in the the year 957, rather than on the day of his death, February 15. Canon O’Hanlon relies on the efforts of the seventeenth-century hagiologist, Father John Colgan, to uncover what was known about the Belgian Saint Columban.
