was there a Chinese word that was some kind of transliteration of “Sodomy?” Did Khan know the Jewish story?
The story of Sodom was well over 3000 years old at his time, so he probably did hear it........
It is almost certain that Ghengis Khan was familiar with Christian Scripture. At least one of the lesser hordes that united under him had converted to Nestorian Christianity (the variety indigeneous to Iraq and Iran, now mostly found in Chicago, which separated from the rest of the Church over objection to the Third Ecumenical Council). That horde had khans with name like “John’ and “George”.
Ghengis Khan’s successor in China, Kublia Khan, sent a Nestorian monk to Europe to propose an alliance between the Christians and the Mongols against Islam. Alas, he ended up in Paris, where the threat of Islam was not so serious as in the Christian East. If he’d turned up in Constantinople, history might have been very different.
