The History of the Great and Mighty Kingdom of China and the Situation Thereof : Volume I (Illustrated)

“The first traveller, from whom accounts collected from personal experience respecting China were received in Europe, was William Van Ruysbroeck, commonly known by the name of De Rubruquis, a friar of the Minorite order, and sometimes called William of Tripoli, from the circumstance of the narrative of his travels having been transmitted from Tripoli to St. Louis, king of France, at whose instance they were undertaken. The cause of his mission was a rumour, which had spread through Europe, that the Mongolian chief, Mangu Khan, had embraced the Christian religion; and St. Louis being then engaged in the fourth Crusade against the Saracens, was anxious to cement an alliance with the Tartars, who were at that time in hostility with the same power on the side of Persia."
