The Martyrology of Tallaght, which is closely related to the Félire Óengusso or Martyrology of Óengus the Culdee, is an eighth- or ninth-century Irish-language martyrology, a list of saints and their feast days assembled by Máel Ruain and/or Óengus the Culdee at Tallaght Monastery, near Dublin.[1] The Martyrology of Tallaght is in prose and contains two sections for each day of the year, one general and one for Irish saints. It also has a prologue and an epilogue.[2]
