These visits, apparently from the Saint Thomas Christians of India, cannot be confirmed, as evidence of both is only available from secondary sources. Later, a letter surfaced during the 1160s claiming to be from Prester John. There were over one hundred different versions of the letter published over the next few centuries. Most often, the letter was addressed to Emanuel I, the Byzantine Emperor of Rome, though some were addressed to the Pope or the King of France. A Latin text with its Hebrew translation reads as follows: "Praete janni invenitur ascendendo in Kalicut in arida..." This is true proof and well-known knowledge about the Jews who are found there near Prester John. Reading the Hebrew letters of Prester John shows that Prester John lived in India; or to be more precise, in Malabar (southern India). Connecting Prester John with India is inevitable from the Hebrew text on the one hand, while parts of the legend will support the Indian origin on the other. Firstly, India is mentioned several times in these letters (pp. 41, 89, 107, 119, and more). Secondly, Kalicut which was one of the most important port cities in Malabar (the place where Vasco da Gama was sent), is mentioned in one of the letters. Thirdly, these facts would definitely suffice, but further evidence appears in the form of this statements: In ... India is buried the body of St Thomas the Apostle. That is, the author knew that St. Thomas was buried in India, a belief held by the Christians of southern India. Not only that, but the author of the letters knew (p. 133) about "St. Thomas holiday", which is, apparently, St. Thomas Memorial Day held by the same Christians on 3 July. Fourth, the author of the letters mentioned that pepper grew in his land (pp. 55, 91, 131), pepper being common in Malabar. Fifth, there are some stories in the letters concerning warriors riding elephants. It is well known that, unlike the African elephant, only the Asian elephant could be trained. Mar Ya'qob Metropolitan of India and Patriarch Yahballaha III At the beginning of the fourteenth century, the Indian church was again dependent upon the Church of the East. The dating formula in the colophon to a manuscript copied in June 1301 in the church of Mar Quriaqos in Cranganore mentions Patriarch Yahballaha III (whom it calls Yahballaha V) and Metropolitan Yaqob of
