English antiquary, ecclesiastical and legal historian best known for his Concilia, Decreta, Leges, Constitutiones, in Re Ecclesiarum Orbis Britannici (“Councils, Decrees, Laws, and Constitutions of the English Church”), which was perhaps the first systematic compilation of church documents. The first volume of the two-part Concilia covered Christianity in Britain until the Norman Conquest (1066) and was published in 1639; the second volume was issued posthumously in 1664. Three times a member of Parliament, Spelman sat on several royal commissions, including the council for New England (from 1620).
