A charter issued by Thomas, Earl of Derby and Lord of Mann, confirming and granting churches, lands, tithes, liberties, and ecclesiastical revenues to Huan, Bishop of Sodor. The document enumerates specific Manx parishes, manorial holdings, fisheries, and judicial privileges, establishing the temporal and spiritual endowments of the bishopric. Provided in both English and Latin versions from Manx Society publications, this is a foundational document for understanding pre-Revestment Manx governance and the power structures of the medieval and early modern Island.
