be paid to him than the fact that he was the one man in Ireland whom everybody trusted. Irish, Vikings, Normans, all had equal respect for him as a man of total honour and integrity. Synod of Cashel The arrival of Henry II of England as Lord of Ireland in Dublin on 11 November 1171 served a number of purposes: first, to rein in his erstwhile Norman subjects before they established a rival Norman kingdom of their own; second, to receive the submission of the Irish kings and princes; third, to arrange a synod at Cashel. This was to bring Ireland in line with Catholic Church observances as practised in Henry's other domains in England and France. Two of the statutes proclaimed concerned the marriage laws of the Irish clergy and the granting of the Rock of Cashel to the church. It was also used to try to bring the Church of Ireland under the jurisdiction of Canterbury and in the process Pope Alexander III confirmed Pope Adrian IV's donation of Ireland to Henry in 1172. The implications of all this only seems to have sunk in after Henry's departure in April 1172 and to this end Ua Conchobair sent Ua Tuathail – accompanied by Catholicus, Abbot of Clonfert — to London to negotiate a settlement with Henry. Treaty of Windsor The Treaty of Windsor was a pact between Ua Conchobair and Henry II which acknowledged Henry's right to the Lordship of Leinster, Meath and such areas then occupied by his Norman subjects. Lorcán was able to get Henry to acknowledge Ua Conchobair's right to the High Kingship and to his lands. However, in so doing, Lorcán had to cede to Henry Ua Conchobair's tribute to him. During the negotiations, Lorcán was saying mass at the shrine of Thomas Becket at Canterbury when he was attacked by a madman. The man had heard of the archbishop's reputation and had the idea of giving the church another martyr; he struck Lorcán on the head, before the altar, with a club. Unlike Becket, Ua Tuathail, though knocked to the ground, was able to recover and finish the mass. Last years and death in Normandy Archbishop Lorcán left Ireland in 1179 to attend the Third Council of the Lateran in Rome, accompanied by five other bishops. From Pope Alexander III he received a papal bull, confirming the rights and privileges of the See
