Saint Fintan was born in Leinster. He received his religious formation in Terryglass, Co. Tipperary under the abbot Colum mac Crimthainn, and was deeply influenced by his penitential practices and the severity of the Rule. Fintan made his own foundation in Clonenagh, Co. Laois. He died in 603. His feast day is on February 17.
His disciples included St Colmán of Oughaval. Though he is sometimes confused with Saint Fintán or Munnu, abbot of Taghmon, they are distinct.
