A 1577 letter from John Merick, Bishop of Sodor and Mann, to an unnamed correspondent (likely Richard Hakluyt) discussing the antiquities, language, history, and governance of the Isle of Man. The letter refutes inaccuracies in Holinshed's Chronicles, defends the Manx language as Greek-derived, explains the island's judicial and administrative structures (Deemsters, Keys), and praises the Earl of Derby's governance. The original Latin text is included alongside the English translation.
