About Blathmac
Lived 750 – 835 (aged 84–85). Blathmac was a monk.
Saint Blathmac was a distinguished Irish monk, born in Ireland about 750 AD. He is known as "Blathmac, son of Flann", to distinguish him from the poet and monk Blathmac mac Con Brettan.
He was killed and became a martyr in Iona, about 825. His biography was written by Strabo, the Benedictine Abbot of Reichenau (824–849), and thus the story of his martyrdom has been handed down.
Early life Blathmac, the scion of a noble family, early showed a religious turn of mind. Strabo describes him as a warrior prince, and "a future king of his people" who gave up his patrimony to enter religious life. His name was Latinized Florentius (from the Irish word bláth meaning "flower").
Career He became the abbot of an Irish monastery, and in 824 left to join the community of monks at Iona which traced itself to Columba.
He was serving as prior or acting abbot in the absence of Diarmait of Iona, who had taken most of the community to Kells for safety. Anticipating yet another viking raid, Blathmac had what remained of the relics of Columba hidden.
His body was afterwards reverently interred at the scene. Miracles are claimed to have been wrought through his intercession. The date of his death is given by the "Annals of Ulster" as 825, although Mabillon places it thirty-six years earlier.
