In 1624 Gunter published a collection of his mathematical works. It was entitled "The description and use of sector, the cross-staffe, and other instruments for such as are studious of mathematical practise." One of the most remarkable things about this book is that it was written, and published, in English not Latin. "I am at the last contented that it should come forth in English," he wrote resignedly, "Not that I think it worthy either of my labour or the publique view, but to satisfy their importunity who not understand the Latin yet were at the charge to buy the instrument." It was a manual not for cloistered university fellows but for sailors and surveyors in real world.
