Báetán moccu Chormaic, abbot of Clonmacnoise, died 1 March 664.
Báetán was a member of the Moccu Chormaic, a prominent line of the Conmaicne Mara (now Connemara). In 653 he became ninth abbot of Clonmacnoise in succession to Aedlug mac Caman. He held office for twelve years, a considerable period considering most candidates were elderly.
He may have been an exegetical scholar. Michael Richter argues that he was a teacher of the Irish "Augustine" (died 665), identifying him with the Bathanus named by Augustine in his De mirabilibus sacrae scripturae.[1]
He was included in the martyrologies, which implies he was considered, at least by some, to be a man of saintly character. He was succeeded by Colmán Cass mac Fualascaig, of the Corcu Moga of what is now north-east County Galway
