1421, El año que China descubrio el mundo

According to Gavin Menzies, New World discovery began before Christopher Columbus was even born. Menzies, a former submarine commander and a full-time amateur historian, has constructed a persuasive case that Chinese exploration reached deeply into the Western Hemisphere and began more than 70 years before 1492. Described by colleagues as "a brilliant maverick," the author contends that the fleet of the eunuch admiral Zheng He circumnavigated the world a full century before Ferdinand Magellan.
