Anastasius I Dicorus was Byzantine emperor from 491 to 518. He made his career as a government administrator. He came to the throne at the age of 61 after being chosen by the wife of his predecessor, Zeno. His religious tendencies caused tensions throughout his reign.
His reign was characterised by improvements in the government, economy, and bureaucracy in the Byzantine Empire. He is noted for leaving the imperial government with a sizeable budget surplus of 23,000,000 solidi due to minimisation of government corruption, reforms to the tax code, and the introduction of a new form of currency. He is venerated as a saint by the Syriac Orthodox Church on 29 July.
