The connection of the Dublin Danes with their brethren in England had long been very close, and it was to Canterbury and Rome rather than to Armagh that they naturally turned. Sitric and Canute were perhaps in the Eternal City together; their visit was at least almost simultaneous, and we cannot doubt that every means were taken to prejudice the powerful neophyte against the pretensions of St. Patrick's successor. An Ostman named Dunan or Donat is reckoned the first Bishop of Dublin, and is credited with the foundation of Christ Church. A tradition which may be true, but which is not supported by contemporary evidence, makes Sitric the joint founder. From an expression in the celebrated letter of the Dublin burgesses to Archbishop Ralph d'Eures it may be fairly inferred that Donat had his succession from Canterbury, and he certainly corresponded with Lanfranc on the subject of infant baptism. He was succeeded by Patrick or Gillapatrick, an Ostman, who was consecrated by Lanfranc in St. Paul's at the instance of Godred Crovan, king of Man, who was then supreme at Dublin. Godred's reign is rather shadowy, but Lanfranc's letter to him has always been considered genuine, and it addresses him as king not only of Dublin, but of Ireland. Lanfranc also wrote to Tirlogh, who had acquired the supreme kingship, like his father, Brian Borumha. It is not unlikely that the curious poem which represents St. Patrick as blessing Dublin and its Danish inhabitants, and cursing the Hy Neill, was forged at this time, partly in the Munster interest and partly to prove that Dublin was not subject to Armagh.[25] [Sidenote: Dublin acknowledges Canterbury and repudiates Armagh.]
