A collection of charter-like records in Latin and Old Irish relating the activities of St Patrick in Ireland and the lands that were granted to him and his church. The collection can be divided into three parts: (1) a text about the foundation of Trim (Co. Meath), including an account of the conversion of Feidlimid son of Lóegaire mac Néill, king of Leinster; (2) a group of six records concerning churches in northern Connacht; and (3) a group of four records concerning churches in Leinster.
Miraculous story which relates how the community of St Éimíne Bán at Ros Glaise (probably Monasterevin, Co. Offaly) received a charter of privileges from the king of Leinster. It is said to have been granted after Éimine and his 49 monks sacrificed their lives to save Bran úa Fáeláin (d. 693), king of Leinster, and 49 chiefs of the province from the plague.
