The above is an extract from a letter which was supposed to have been sent from Prester John to Emanuel of Constantinople in 1165. The reference to Thomas the Apostle highlights the tradition that he travelled as far as present day Indian states of Kerala and Tamil Nadu to preach the gospel. Nowadays, we tend to think of medieval Christianity as split into two camps: the Roman Catholic Church and the Orthodox Church based in Constantinople, but there was a third, greater in geographical extent than either of the other two. This was the Church of the East, or Nestorian Church which had split from the western Church following the Council of Ephesus in 431. Its reach, from the ninth to the fourteenth century extended from the Mediterranean, through modern Iran and Iraq and on to India, China and was present and influential within the Mongol Empire as it expanded in the thirteenth century.The Second Crusade,which ran from 1147 until 1149, had been a failure and it seemed that the Christian presence in the Holy Land was under immediate and serious threat. Rumours started to spread that, somewhere to the east, lay an enormous and powerful Christian power which might be called upon for aid.
Otto of Freisingen was perhaps the first to talk about the empire of Prester John. He wrote in his chronicle that, in an audience with the Pope in 1145, a Catholic Bishop stated:
"...that a few years ago a king and Priest named John, who lives beyond Persia and Armenia, in the remote East, and who, and all of his subjects, were Christian, though belonging to the Nestorian Church..."
The text goes on to record Prester John's victory over the Persians and that he had gone on to march his army west to aid the Church at Jerusalem but had had to turn back when he could not cross the Tigris.
Pope Alexander III is supposed to have written a letter to the mysterious Emperor, in 1177, which he entrusted to his physician, Philip, to deliver by hand. Philip never returned. Later, in 1241, the Mongols reached the Danube and might have gone on to threaten the whole of the European subcontinent if they had not pulled back. Contact and convesation with Nestorian Christians among the Mongols revealed that they knew nothing at all of such a person as Prester John.
Gradually, people came to realise that Prester John's domains could not be in the area first supposed, but this did not mean that he did not exist. There was another Church territory where he must be, Ethiopia.
