 Of these last, the "Frithfolad Muman", a document purporting to set out the obligations of the Kings of Munster to their allies, clients, and subjects is of interest as it sheds light on the position of Osraige within the provincial kingship of Munster.A memory of the kingdom of Osraige survives today in the name and boundaries of the Roman Catholic Diocese of Ossory.The earliest recorded seat of the bishops was at Saighir, later moved to Aghaboe, and this appears to have been the principal church of the kingdom by the eighth century when the life of Saint Cainnech of Aghaboe was composed.
