Between the late 1600s and mid-1800s, there was no Western presence on Taiwan. There were, however, a couple of special Western visitors of whom the wonderfully-named Joseph-Anne-Marie de Moyriac de Mailla was the most notable. This Jesuit priest was a hardcore scholar who spent 45 years in China. Emperor Kangxi gave de Mailla and fellow Jesuits a mission: "Go map my empire... including Taiwan!" This is the story of what the esteemed Jesuit priest saw when he visited Formosa in 1714.
