During his tenure of this chair he published two mathematical works of great learning and elegance, the
first on Geometry and the second on Optics. In 1669 he resigned in favour of his pupil, Isaac Newton,
who was long considered his only superior among English mathematicians. About this time also he
composed his Expositions of the Creed, The Lord’s Prayer, Decalogue, and Sacraments. He was made
a D.D. by royal mandate in 1670, and two years later Master of Trinity Coll., where he founded the library.
Besides the works above mentioned, he wrote other important treatises on mathematics, but in literature
his place is chiefly supported by his sermons, which are masterpieces of argumentative eloquence,
while his treatise on the Pope’s Supremacy is regarded as one of the most perfect specimens of controversy
in existence. Barrow’s character as a man was in all respects worthy of his great talents, though he had
a strong vein of eccentricity. He died unmarried in London at the early age of 47. Barrow’s theological
works were edited by Napier, with memoir by Whewell (9 vols., 1839).
