A 12th-century royal charter by Olave (Olaf), King of the Isles, granting ecclesiastical authority and land to the Church of St. Mary of Furness in relation to the Isle of Man. The charter establishes episcopal independence and Christian observance under a bishop rather than foreign clergy. Provided in parallel Latin and English transcription, this document is foundational to understanding medieval Manx ecclesiastical governance and the island's early constitutional relationship with the papacy and the Church.
