A couple of thousand years ago, or even longer depending on which book you read, the Mosuos, originally known as the Na people, walked from the high mountains in the north-west to where they are today, in search of a kinder climate. They must have trekked for years and years, passing over countless harsh mountain ranges before coming across a great plateau situated in a lower altitude, much more hospitable than their previous homeland.
Andrés de Urdaneta is a name that few other than specialist historians will immediately recognise. He was one of the last of the fifteenth- and sixteenth-century explorers and navigators from the Iberian peninsula whose voyages resulted in redrawing the globe in more or less the form we know it today. Christopher Columbus has a country and several cities named after him; Ferdinand Magellan has the famous straits. But Urdaneta has no such monuments.
Perhaps this is because Urdaneta didn’t discover how to get anywhere, but rather less glamorously but no less importantly discovered how to get back. Until 1565, no fleet had succeeded in sailing east from Asia back across the Pacific to the Americas. It was Urdaneta, a survivor of earlier expeditions, who first worked out the right winds and currents across the uncharted waters of this vast ocean. His discovery was called the tornaviaje, or ‘return trip’.
