periplus
n. a circumnavigation, an epic journey, an odyssey

In 1505 Ferdinand Magellan sailed east to Malaysia, where he acquired a slave named Enrique who accompanied him on his subsequent westward circumnavigation of the globe. When that expedition reached the Philippines, Enrique escaped, and his fate is lost to history. That’s intriguing: If he managed to travel the few hundred remaining miles to his homeland, then he was the first person in history to circumnavigate the earth.
