Giovanni Francesco Gemelli Careri (1651–1725) was an Italian adventurer and traveler. He was among the first Europeans to tour the world by securing passage on ships involved in the carrying trade; his travels, undertaken for pleasure rather than profit saw him travel through the Middle East, India, China and the New World within a span of five years. Some suspected him of spying for the Vatican (or rather for the Jesuits) on his journey. The reliability of his travels were once doubted, but is now considered to be authentic due to the details observed in his writings.
