Fernão Mendes Pinto. Portuguese traveler. He composed an autobiographical work that became a classic of sea travel, called Peregrinação, or Pilgrimage, which was published only in 1614. During his 21 years of travel, he was shipwrecked and enslaved a number of times. Java, Japan (where he may have been first to introduce firearms) and China were among the countries he visited. He was taken away by Altan Khan when he attacked Peking.

It is said that he made a later trip to Japan in 1547 and carried off a Japanese named Anjiro, said to have been the first Japanese convert to Christianity.
