A bilingual (Latin/English) transcription of a 12th-century royal letter from Olave II, King of the Isles (Hebrides and Isle of Man), to the Dean and Chapter of York requesting the consecration and return of his bishop-elect, Nicholas. The document demonstrates the ecclesiastical jurisdiction and political relationship between the Manx kingdom and English church authority, and establishes the historical precedent of Isle of Man's constitutional status within broader British isles governance.
