Like Columbus, Ferdinand Magellan thought that Europeans could reach the Far East by sailing West. He aspired to dominion, displaying military prowess, navigational skill, powers of persuasion and unwavering determination. Bettering Columbus, his venture led to the circumnavigation of the world by European seamen, the most audacious in maritime history. He proved his theory possible, dying in the process. 500 years have now passed since Magellan’s voyage. Allen Mawer closely examines the historical sources, charts and eyewitness records and considers afresh what we can know of Magellan and the details of his voyage.
