Regarding the first edition, "his notes were edited by his Ordnance second clerk, Nicholas Stephenson, to form a pocket-book, Mathematical Compendium (1674)." (DNB)

"Handbook of applied mathematics first published in 1674, including instructions for using the elementary mechanical calculating device known as "Napier's Bones," a distant forerunner of the computer, developed in the early 1600s by John Napier, the inventor of logarithms." (Swann Galleries)

"Sir Jonas Moore (1617-1679) was a practical mathematician, teacher, and author who, when unable to make a living as a tutor and professor of mathematics, rose to prominence in the Restoration court of Charles II, after demonstrating his value as a surveyor and cartographer. On being appointed to the high office of Surveyor General of the King's Ordnance, he used both his income and his influence with the King to become a patron of navigational astronomy. An able mathematician (he is best known for his work in trigonometry and the development of the 'cos.' in mathematical equations), his enduring importance derives from his strong support of mathematics and astronomy which made many other mathematical and astronomical advances possible."
