Mayer, John D.D., an English divine, flourished in the early part of the 17th century. But few memorials have been discovered to furnish any satisfactory account of his personal history. It appears from his prefaces that he labored under infirm health, which unfitted him for public services as a clergyman for many years. In 1634 he became minister of Reydon, in Suffolk. He published Theological Treatises and Commentaries on the English Catechism (Lond. 1621, 4to): — A Commentary on the Old and New Testaments (rare; 6 vols. fol., and 1 vol. 4to, 1631, '47, '52, '53).
