A detailed revenue account (compotus) of the demesne lands and income of Rushen Abbey on the Isle of Man, recorded during the reign of Henry VIII. The document lists farm rents, land parcels with acreage, mill rents, and rectory farms across multiple Manx parishes. It provides valuable evidence of monastic landholding and economic organisation before the Reformation, relevant to understanding pre-Revestment Manx economic structures and property rights.
