Zeno the Isaurian (; ; ; c. 425 – 9 April 491), originally named
Tarasis Kodisa Rousombladadiotes , was
Byzantine Emperor from 474 to 475 and again from 476 to 491. Domestic revolts and religious dissension plagued his reign, which nevertheless succeeded to some extent in foreign issues. His reign saw the end of the
Western Roman Empire under
Romulus Augustus, but he contributed much to stabilizing the eastern Empire.
