If you ask most people to name the first person to circumnavigate the globe, they will likely answer Ferdinand Magellan, the Portuguese mariner who sailed on behalf of Spain in 1519. But Magellan never even attempted the feat, and he didn’t live to see it accomplished by members of his crew. As we approach the 500th anniversary of their achievement next month, Felipe Fernández-Armesto, a professor of history at the University of Notre Dame and author of contrarian works such as “1492,” “Amerigo” and “The Spanish Armada,” takes exception to the “tradition of hero worship” that persists around Magellan. In “Straits: Beyond the Myth of Magellan,” he launches his broadside.
