Alopen

Alopen (Chinese: 阿羅本, fl. AD 635; 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.
