Cardinal Vivian now proceeded to Dublin, where he held a synod. The principal enactment referred to the right of sanctuary. During the Anglo-Norman wars, the Irish had secured their provisions in the churches; and it is said that, in order to starve out the enemy, they even refused to sell at any price. It was now decreed that sanctuary might be violated to obtain food; but a fair price was to be paid for whatever was taken. It is to be feared these conditions were seldom complied with. The Abbey of St. Thomas the Martyr was founded in Dublin about this time, by FitzAldelm, at the command of Henry II., one of his many acts of reparation. The site was the place now called Thomas Court. The Viceroy endowed it with a carnucate of land, in the presence of the Legate and St. Laurence O'Toole. After the settlement of these affairs, Cardinal Vivian passed over to Chester, on his way to Scotland. One of Roderic O'Connor's sons, Murrough, having rebelled against him, Miles de Cogan went to his assistance,--a direct and flagrant violation of the treaty of Windsor. At Roscommon the English were joined by the unnatural rebel, who guided them through the province. The King was in Iar-Connaught, and the allies burned and plundered without mercy, as they passed along to Trim. Here they remained three nights; but as the people had fled with their cattle and other moveable property into the fastnesses, they had not been able to procure any spoil on their march. Roderic soon appeared to give them battle; but they were defeated without considerable loss. Murrough was taken prisoner by his father, and his eyes were put out as a punishment for his rebellion, and to prevent a repetition of his treachery.
