The case
Our case: Columbus's fleet carried a Hebrew and Chaldean (Aramaic) speaker because the Spanish were hunting the Great Khan and Prester John in 'the Indies,' and the Khan's court had Aramaic-praying Christians, Prester John among them. They sailed west to find India Superior and Prester John's realm, and they landed here.
Background
Tito, Nov 12, 2026: "they were trying to find India, the true home of Prester John." Prester John was a Christian priest-king whom medieval Europeans believed ruled a realm in the East. The Church of the East, called 'Nestorian' by its rivals, prayed in Syriac, a form of Aramaic, the old language of the Near East; 'Chaldean' is an old name for that Aramaic. A metropolitan is a senior bishop. The Yuan were the Mongol rulers of China, the Great Khans, and Khanbaliq was their capital. Edessa and Mesopotamia are in the Near East, Kerala is in south India, and the Kerait and Öngüt were peoples of the Mongol lands. India Superior is the old maps' name for the far Indies.
Our evidence
Exhibit A · Record: Otto of Freising: Prester John a NestorianOtto of Freising (1145) calls Prester John a Nestorian Christian (P887): a member of the Church of the East, whose prayer language was Syriac, a form of Aramaic, from Edessa and Mesopotamia to Kerala and China.
Exhibit B · Record: The church in China and IndiaThe Xi'an stele (781), an inscribed stone, records that church in China from 635. The Saint Thomas Christians of India kept the East Syriac liturgy, their order of prayer, for over a thousand years.
Exhibit C · Record: At the Great Khan's capitalUnder the Yuan Mongols the church had a metropolitan in Khanbaliq, the Great Khan's capital. The Kerait and Öngüt were Christian peoples. About 1275 Rabban Sauma and Marqos (later Yahballaha III) set out from Khanbaliq for the West. Source: Gorgias Encyclopedic Dictionary of the Syriac Heritage.
Exhibit D · Record: The nearest real Prester JohnToghrul of the Kerait, a Nestorian, is the nearest real Prester John (P890).
Exhibit E · Pattern: The record's own logicThe Great Khan's court had Aramaic-praying Christians, and Prester John was one of them; so a Spanish fleet hunting the Khan and the priest-king in 'the Indies' had every reason to carry a Hebrew and Chaldean (Aramaic) speaker (P909). This is the record's own logic, not a guess.
Exhibit F · Our lens: They landed hereOur WW9 lens, from Tito: they sailed west to find India Superior and Prester John's Aramaic-speaking realm, and they landed here. Amor and Roma, A-M-R and R-M, the same letters running both ways (P907).
Exhibit G · Open: The orders that name the purposeOpen, needs deep research: Spanish and Portuguese orders, letters or crew lists naming the Syriac-Christian purpose of the interpreter, in the Archivo de Indias and the Torre do Tombo, the Spanish and Portuguese royal archives.
Verdict: winning
The Record places Aramaic-praying Christians at the Great Khan's capital and names Prester John a Nestorian, and the Pattern follows: a fleet hunting the Khan and the priest-king had every reason to carry a Chaldean speaker. The case is winning, not won, because no order, letter or crew list yet found names the interpreter's Syriac-Christian purpose in the colonizers' own words.
Next exhibit: Spanish and Portuguese orders, letters or crew lists in the Archivo de Indias and the Torre do Tombo that name the Syriac-Christian purpose of the interpreter.
