The sole edition of an evaluation of the gospels in regards to the Nativity and the early life of Christ, written, with the aim of ascertaining the true year of the Saviour's birth, by mathematician Charles Hayes (1678-1760) after having for some years applied himself to the study of Hebrew. Hayes is primarily remembered for his Treatise of Fluxions, or, An Introduction to Mathematical Philosophy (London, 1704); the first English work to explain Newton's method of fluxions - the Newtonian version of the infinitesimal calculus.
