It was also in the time of this Muircheartach that a synod or National Council was convened in Ireland at Raith Breasail in the year of the Lord 1100, according to an old book of annals of the church of Cluain Eidhneach Fionntain in Laoighis, in which are recorded the principal things done at that synod; and Giolla Easpuig, bishop of Luimneach, who was the Pope's legate in Ireland at that time, was president of that council. Now here follow the regulations that were made therein:
Just as twelve bishops were fixed under Canterbury in the south of England, and twelve bishops in the north under the city of York, a similar arrangement was made at the synod of Raith Breasail in Ireland, to wit, twelve bishops in Leath Mogha and twelve bishops in Leath Cuinn and also two bishops in Meath. It was at this synod that the churches of Ireland were given up entirely to the bishops free for ever from the authority and rent of the lay princes. It was there also were regulated the sees or dioceses of the bishops of Ireland. Here is the full number of the bishops of Leath Cuinn: six in the province of Ulster, including the primate; five in the province of Connaught, and two in Meath. And this gives the full twelve bishops of Leath Cuinn excluding the primate. The following are the dioceses of the province of Ulster, to wit, Ard Macha, the see of the archbishop of Ard Macha and primate over the bishops of all Ireland, Clochar, Ard Sratha, Doire, Cuinneire, and Dun da Leathghlas; the sees of Meath, Daimhliag and Cluain Ioraird; the sees of the province of Connaught, namely, Tuaim da Ghualann, Cluain Fearta Breanainn, Conga, Cill Aladh, and Ard Charna; the sees of Munster, Cashel held by the archbishop of Leath Mogha, Lios Mor or Port Lairge, Corcach, Raith Mhaighe Deisceirt, Luimneach, Cill Dalua, Imleach Iobhair. These were the seven sees which were decreed to Munster at this synod. Five sees in Leinster, Cill Chainnigh, Leithghlinn, Cill Dara, Gleann da Loch, Fearna or Loch Garman. Adding these five sees to the seven sees of Munster they make twelve sees in Leath Mogha. The reason why Ath Cliath is not counted here is that it was not customary with its bishop to receive consecration except from the archbishop of Canterbury in England.
Hanmer states falsely that the archbishop of Canterbury had jurisdiction over the Irish clergy from the time of Augustine the monk until the Norman Invasion. For you will not find that the prelates of Canterbury had. jurisdiction over the Irish clergy except in the time of Lanfrancus Ranulphus and Anselmus; and even then the portion of the clergy of Ireland over whom they had jurisdiction were the clergy of Ath Cliath, Port Lairge, Loch Garman and Luimneach who were descended from the remnant of the Lochlonnaigh who were called Normani, and it was through a feeling of friendship for the people of Normandy who sprang from their own race that the prelates of these places gave jurisdiction and authority to the archbishop of Canterbury over them, as is clear from the booklet written by Dr. Ussher, for they considered if there were to be an election by the people between themselves and one of the Gaels who sought the same dignity, that their side would not have an equal chance, as in the election the Gael would have a larger popular vote than any of them.
I think that although the old book does not so state, it was six bishops that were in Munster and six in Leinster, with the archbishop of Cashel over them all as chief prelate of Leath Mogha after the manner of the temporal sovereignty as we have said above in treating of this matter in the reign of Laoghaire.

If the Connaught clergy agree to this division, we desire it, and if they do not, let them divide it as they choose, and we approve of the division that will please them, provided there be only five bishops in Connaught.
The see of the archbishop of Cashel, from Sliabh Eibhlinne to the Siuir and from Cnamhchoill at Tiobrad Arann eastward to Grian Airbh, that is Cros Ghreine.
