Prince henry "the navigator" (Yale University Press)

This enthralling life of the legendary fifteenth-century Portuguese prince, Henry the Navigator, is the first comprehensive biography in more than a century. Examining the full range of the prince's activities as an imperialist and as a maritime, cartographical and navigational pioneer, Peter Russell shows that while Henry was firmly rooted in medieval times, his innovations set in motion changes that altered the history of Europe and regions far beyond.
