Prester John (Latin: Presbyter Johannes) was a legendary Christian patriarch, presbyter (elder) and king who was popular in European chronicles and tradition from the 12th through the 17th centuries. He was said to rule over a Nestorian (Church of the East) Christian nation lost amid the Muslims and pagans of the Orient, in which the Patriarch of the Saint Thomas Christians resided. The accounts are varied collections of medieval popular fantasy, depicting Prester John as a descendant of the Three Magi, ruling a kingdom full of riches, marvels, and strange creatures.
At first, Prester John was imagined to reside in India; tales of the Nestorian Christians' evangelistic success there and of Thomas the Apostle's subcontinental travels as documented in works like the Acts of Thomas probably provided the first seeds of the legend. After the coming of the Mongols to the Western world, accounts placed the king in Central Asia, and eventually Portuguese explorers convinced themselves that they had found him in Ethiopia.
