A royal letter patent from Queen Elizabeth I granting assent to the nomination of John Mericke (M.A.) as Bishop of the Isle of Man, following the death of Bishop John Salesbery. The document affirms the Earl of Derby's hereditary right of patronage over the Manx bishopric and directs the Archbishop of York to confirm, consecrate, and invest Mericke. It demonstrates the overlapping jurisdiction of the Crown, the Earl of Derby, and the Church over Man's ecclesiastical affairs.
