Description
hardcover with coloured dust-jacket, 368pp. Two double-page maps of “The North Atlantic” and “The Pacific” This is the story of an instrument that changed the world. In prose as crisp as the book’s subject, David Barrie tells how and why the sextant was invented; how offshore navigators depended on it for their lives in wild and dangerous seas until the advent of GPS – and the sextant’s vital role in the history of exploration.
