are certainly names on the island from both languages, including "Tarbet" (tairbeart, an isthmus), "St Colme's Hole" (Colm Cille) and "Ardchattan" from Gaelic, and "Kirkhaven" which may refer a Norse original "Kirkshavn". It is also thought that the name may refer to the use of the island by the Maeatae as a royal burial site. The island was the site of one of the earliest Christian churches in Scotland, founded in the 9th century and built into an unusual mass-burial mound that probably dates from prehistoric times. Although radiocarbon dating of bones reveal them to date from the 7th century to the 10th century, remains of Bronze Age funeral urns suggest that the mound may be older. The current chapel on the site is dedicated to Saint Adrian of May, who was killed on the island by Danish invaders in 875. The thirteenth-century Orkneyinga saga records another Viking raid, by Sweyn Asleifsson, and Margad Grimsson, after they had been expelled from Orkney by Earl Rögnvald, when they went raiding on the eastern seaboard of Scotland: However, no abbot of the name Baldwin was recorded. There may be some conflation with St Baldred, who is connected with the nearby Bass Rock, and St Baldred's Boat off Dunbar. Another possible mention of the island is under the name "Mosey". This may be a conflation with Mousa (properly Mosey), since it comes close to a mention of "Moseyjarborg" (the Broch of Mousa), or a mistranscription of "Maey" in the old script. It is also suspiciously similar to the previous extract. "They put into Mosey, and Swein sent men to Eidinaborg (Edinburgh), to tell the King of Scots of their plunder." The original church was expanded during the 12th century by David I of Scotland, under the aegis of Reading Abbey which had been founded by his brother-in-law, Henry I of England and thus a Benedictine community was established. The monks agreed to maintain nine priests on the island to pray for the souls of the Kings Of Scots. The island, with the supposed relics of Ethernan who died there in around 669, was a popular destination for pilgrims during the later Middle Ages. Evidence that it was already an important place for pilgrimage in the 12th century include the remains of a ten-seater communal lavatory, much larger than necessary for an abbey with only nine or ten monks.
