Antonio Pigafetta was a Venetian scholar and explorer. He joined the Spanish expedition to the Spice Islands led by Portuguese explorer Ferdinand Magellan, the world's first circumnavigation, and is best known for being the chronicler of the voyage. During the expedition, he served as Magellan's assistant until Magellan's death in the Philippine Islands, and kept an accurate journal, which later assisted him in translating the Cebuano language. It is the first recorded document concerning the language.

Ferdinand Magellan was a Portuguese explorer best known for having planned and led the 1519 Spanish expedition to the East Indies across the Pacific Ocean to open a maritime trade route, during which he discovered the interoceanic passage thereafter bearing his name and achieved the first European navigation to Asia via the Pacific. After his death, this expedition was the first to circumnavigate the globe in 1519–22 in the service of Spain.
