Alopen

Alopen (, ; also "Aleben", "Aluoben", "Olopen," "Olopan," or "Olopuen") is the first recorded Christian missionary to have reached China, during the Tang dynasty. He was a missionary from the Church of the East, and probably a Syriac speaker from the Sasanian Empire or from Byzantine Syria. He is known exclusively from the Xi'an Stele, which describes his arrival in the Tang capital of Chang'an in 635 and his acceptance by Emperor Taizong of Tang. His is the earliest known name that can be attached to the history of the Church of the East in China.

This may be a transliteration of the Semitic "Abraham" or aloho punoya, "the conversion of God." Amy Chua posits that his name could be a transcription of "Ruben", Alexis Balmont rather advocates for Ardaban.
