Richard Sault died in Cambridge in May 1702. Though he was described as a ‘gentleman’ and exceptionally well equipped in mathematics, as well as Latin and French, the details of Sault's background and education are not known. His connections were with dissenting families, however, and he may have been a product of one of the early dissenting academies, possibly Morton's in Newington Green, where a rigorous intellectual training with a slant to modern philosophy was available. For a while he ran a ‘mathematick school’ near the Royal Exchange in London. He married the half-sister of the publisher John Dunton, who provided him with literary work and involved him as a main contributor to his Athenian Mercury (initially called the Athenian Gazette). This magazine was published from 1690 till 1697 and sought to cater to the burgeoning interest of laypeople in ‘nice and curious questions’, including those raised by new developments in science and philosophy. Sault wrote particularly on mathematics, surveying, physics and astronomy, and showed a good knowledge of the work of Descartes, Leibniz and Newton.
