"Variably genial, cautionary, lyrical, admonitory, terrifying, horrifying and inspiring...A lifetime of thought, travel, reading, imagination and memory inform this affecting account." --Kirkus Reviews(starred review) Blending history and anecdote, geography and reminiscence, science and exposition, New York Timesbestselling author Simon Winchester tells the breathtaking saga of the Atlantic Ocean. A gifted storyteller and consummate historian, Winchester sets the great blue sea's epic narrative against the backdrop of mankind's intellectual evolution, telling not only the story of an ocean, but the story of civilization. Fans of Winchester's Krakatoa, The Man Who Loved China, and The Professor and the Madmanwill love this masterful, penetrating, and resonant tale of humanity finding its way across the ocean of history.
A pair of books called The Atlantic and The Pacific; detailing the history of the ocean, people in it and around it. The Perfectionists, about precision engineering
Simon Winchester discusses how Cape Bojador [1] was impassible until 1443 (in his book Atlantic [2]) so it is unlikely that early voyages reached any further south along the coast of West Africa. During Roman times there were indeed canals to the Red Sea [3] and a robust international trade system as outlined in the Periplus of the Erythraean Sea [4].
