The Martyrology of Tallaght is contemporary with that of Oengus (vol. 29 in this series) and served as the latter's source. Tallaght monastery, close to Dublin, was founded by Maelruain (d. 792), and his disciple Oengus wasa member of the community. The Stowe Missal (vols 31 and 32 in this series) also has a Tallaght provenance. Dated to c. 797-808, the Martyrology of Tallaght is the earliest Irish compilation of its kind, but seems to have aimed at a full list of saints from the Roman Calendar. Under each day is given an entry in Latin followed by a supplement in Irish. The principal manuscript is the Book of Leinster. The many marginal notes and poems of themanuscript are reproduced here, and the edition contains a wealth of notes and very full indexes.
