2 Ibn Battuta (1304-1368)
Ibn Battuta was a Moroccan scholar and explorer who travelled extensively in Afro-Eurasia for over 30 years, with a total travel distance amounting to 72,000 miles.
He toured China from 1345 to 1346, and was the first to introduce China, especially the Great Wall, to the Western and Arab worlds. Ibn Battuta was generally regarded as one of the greatest travelers of all time, and he later detailed his journeys in a book called The Rihla, which has guided numerous historians and travelers.
