John the Elder
Presbyter John, Preter John
He is first mentioned by the chronicler Otto of Freising who says he attacked Ecbatana and defeated the Medes and Persians, whose capital it was. A spurious letter of Prester John, describing the wonders of his kingdom, appeared in Europe (perhaps in 1185) and became vastly popular. Marco Polo identified him with an Asiatic ruler, but Jordanus de Sévérac (fourteenth century) placed him in Ethiopia. His legend was so strong in the Middle Ages that successions of popes attempted to communicate with him for centuries.
