Chaucer's Astrolabe - The Medieval GPS

Available for over a year

Philip Ball tells the story of Chaucer's Astrolabe and why the famed poet came to write the world's first scientific instruction manual. In the Middle Ages, no self respecting astronomer would be without an Astrolabe, a pocket sized device for working out the movements of the planets and stars. So how did a poet come to write the first user booklet? This story shows Chaucer in a new light: as a pre-eminent astronomer, and offers a new key to unlocking his most famous literary works.
