"Student."—Prester John, or "Priest John," is the name given to a personage who was supposed to hold the position of priest-king over a Christian tribe somewhere in the interior of Asia. Prester John is often mentioned in the literature of the Middle Ages, but historians consider him a mythical character, as no record of his existence has ever been discovered. So strong was the belief in him, however, that about the middle of the thirteenth century St. Louis, King of France, sent an embassy in search of him and his isolated Christian people. The embassy met with no success, but it was still believed that Prester John dwelt securely in some remote region. The legend of his existence is supposed to have arisen from the fact that, during the eleventh and twelfth centuries parties of Nestorian missionaries visited the interior of Toorkistan, and converted a powerful Khan to Christianity. Their glowing accounts of the magnificence of his court, and of the sincere piety of him and his people, made so strong an impression as to give color to all the legends of that period. The Khan was overthrown and killed in 1202, and Christianity in his dominion ceased, but the existence of Prester John was still believed in, and for several centuries devout monarchs continued to send embassies in search of him and his Christian brotherhood.
