About Ciarán of Clonmacnoise

Lived 516 – 546 (aged 29–30). Ciarán of Clonmacnoise was an Irish catholic priest and catholic bishop.

Saint Ciarán of Clonmacnoise (c. 516 – c. 549), supposedly born Ciarán mac an tSaeir ("son of the carpenter"), and the first abbot of Clonmacnoise. He is sometimes called Ciarán the Younger to distinguish him from the 5th-century Saint Ciarán the Elder who was bishop of Osraige. His name produced many variant spellings, including Ceran, Kieran, Kyran, Queran and Queranus.

Life

Ciarán was born in around 516 in County Roscommon, Connacht, in Ireland. As a boy, Ciarán worked as a cattle herder.

He was a student of Finian's at Clonard and in time became a teacher, himself. As abbot, he worked on the first buildings of the monastery; however, he died about seven months later of a plague, in his early thirties.

One story tells that he lent his copy of the Gospel of St Matthew to fellow-student St Ninnidh. When Finnian tested the class, Ciarán knew only the first half of the Gospel. The other students laughed and called him "Ciarán half-Matthew." St Finnian silenced them and said, "Not Ciarán half-Matthew, but Ciarán half-Ireland, for he will have half the country and the rest of us will have the other half."

Saint Ciarán of Clonmacnoise has a strong connection with Campbeltown, Argyll and Bute in Scotland. Campbeltown was formerly known as Ceann Loch Chille Chiarain which means "head of the loch by the kirk of Ciarán" Pilgrims frequently take place were tourists visit a cave associated with the Saint near Island Davaar. The Saint is believed to have lived for a time in an area that would later become known as Campbeltown at the same time as the legendary king Fergus Mór was establishing the kingdom of the Scottish Dál Riata, after invading Argyll from Ireland.
