Roolwer
Bishop of the Isles
About Roolwer
Stained glass in Kirk Maughold depicting bishop Roolwer (circa 1900). Roolwer, also known as HrĂłlfr, was an eleventh-century ecclesiast. He is the first named bishop of a jurisdiction which later became the Diocese of the Isles, and appears to have served at his post before, and perhaps during, the reign of Gofraid CrobĂĄn, King of Dublin and the Isles. Roolwer's name appears to correspond to the Old Norse HrĂłlfr, which could mean that he is identical to either of two contemporary like-named bishops of Orkney. Roolwer's predecessor in the Isles may have been DĂșnĂĄn, whose death in 1074 during the Dublin overlordship of Toirdelbach Ua Briain, King of Munster, may have enabled the ecclesiastical separation of Dublin from the Isles. The site of Roolwer's cathedral is unknown, although Maughold and St Patrick's Isle are possibilities.
Attestation
One of several ruinous keeills in the churchyard of Kirk Maughold. According to the chronicle, Roolwer was buried at the "church of St Maughold". Whether this was the site of his cathedral is unknown.
The ecclesiastical jurisdiction of the Kingdom of the Isles, from the mid twelfth century at least, was the Diocese of the Isles. Little is known of the early history of the diocese, although its origins may well lie with the UĂ Ămair imperium. The episcopal succession of the Isles, as recorded in the Chronicle of Mann, starts its chronology at about the time of the reign of Gofraid CrobĂĄn, King of Dublin and the Isles. The first bishop to be named in the chronicle is Roolwer himself, and the form of his name preserved by this source suggests that his name is a garbled form of the Old Norse HrĂłlfr. The chronicle states that Roolwer was the bishop before Gofraid CrobĂĄn's reign,
Contemporaries
The eleventh-century stone tower on St Patrick's Isle may have been erected by Roolwer, and the island itself may have been site of his episcopal seat.
Roolwer's recorded name may be evidence that he is identical to one of the earliest bishops of Orkney. Specifically, either Thorulf (fl. 1050) or Radulf (fl. 1073). Considering the early eleventh-century Orcadian influence in the Isles, it is not inconceivable that the near contemporaneous Church in the region was then under the authority of an Orcadian appointee. In fact, the Annals of Ulster instead accords him the title "ardespoc Gall" ("high-bishop of the Foreigners"), and the first Bishop of Dublin solely associated with Dublin is Gilla PĂĄtraic, a man elected to the position by the Dubliners during the regime of Toirdelbach Ua Briain, King of Munster and Gofraid mac AmlaĂb meic Ragnaill, King of Dublin. It is unknown if DĂșnĂĄn or Roolwer himself were consecrated by the Archbishop of Canterbury, although Radulf apparently received consecration from the Archbishop of York in about 1073. The site of Roolwer's cathedral is also unknown, although it may have been seated on St Patrick's Isle. a man whose Anglo-Norman or French name may cast light on his origins, and may in turn reveal Gofraid CrobĂĄn's links with the wider Anglo-Norman world. Indeed, such connections would seem to parallel those between Dublin and the Archbishop of Canterbury, forged by Gofraid CrobĂĄn's aforesaid contemporaries in Dublin, Toirdelbach and Gofraid mac AmlaĂb meic Ragnaill.
