The Mariner’s Magazine, or Sturmy’s Mathematical and Practical Arts, London, 1669, was compiled and published by Samuel Sturmy (1633–1669). Sturmy was a British sea captain and respected authority on navigation and seamanship. Above, the frontispiece bears Sturmy’s portrait and the title page bears illustrations of the nautical instruments discussed in the book. The feature “calculation” is listed in the content description, indicating a recognition of the importance of mathematics in the tasks of navigation. This image was obtained through the courtesy of the Yale Center for British Art, Paul Mellon Collection.

This chart, titled “The Most Excellent Gunner” and designed for naval gunnery, is from The Mariner’s Magazine. By the 17th century, naval gunnery started to become something of a science dependent on the use of mathematical data. Sturmy’s chart provided such data at a time when the British navy was coming into its own. The average gunner was most likely illiterate and such references were intended for gunnery officers. This image was obtained from Yale University’s Beinecke Rare Book and Manuscript Library.
