" Sails and Shadows is the first account of Portuguese voyaging ever to incorporate data and insights from modern sciences as well as from aged texts. Based on an impressive engagement with original sources in multiple European languages, it should stand (for a very long time) as the definitive English-language account of its subject, which is an important one for world history, maritime history, and European history."--J. R. McNeill, author of Mosquito Empires "Patricia Seed has produced an outstanding and truly original account of early Portuguese seaborne exploration down the west coast of Africa and to India. The book's great innovation is its deep and learned engagement with the growing field of climate history, which contextualizes Portuguese navigation, colonization, and settlement."--Jerry Brotton, author of Four Points of the Compass: The Unexpected History of Direction "Scrupulously researched, elegantly written, and, most importantly, unfailingly fascinating, Seed's fine book reminds us of the sheer tenacity and bravery of the early Portuguese blue-water navigators. She is especially good at telling of the heroic sailor Gil Eanes, who managed to weave his caravels around the shoals and treacherous currents that blocked passage past West Africa's notorious Cape Bojador, thereby finally opening the Atlantic--and thence the Indian and Pacific Oceans--to those deep-water mariners who would help bend much of the sixteenth-century planet to Lisbon's command.

As with most European colonial expansion, the subsequent years were marked by excess and cruelty. But about the skillful early seamanship there can be no argument. Such adventuring, whatever the human consequences, also left Portugal with a uniquely maudlin aphorism, still to be heard muttered in dockside bars today: So small a country to live in, but the whole world to die in.
