An Shigao
During the Qin and Han Dynasty, the most common origin of the surname An was as a contraction of Anxi, meaning "Arsacid", and was thus given to people of Arsacid-territory origin, such as An Shigao, a nobleman from the Arsacid Empire. An Xuan, another Parthian, followed An Shigao to Luoyang and assisted in his translations of Buddhist texts.
