Anastasius I (reigned AD 491–518) was one of the most successful and transformative emperors in Roman/Byzantine history. Often called Anastasius Dicorus (the “Two-Pupilled”) because of a rare condition called heterochromia—one of his eyes was blue and the other black—he is remembered as the “Financial Architect” of the Empire.
1. Rise to Power
Anastasius was not born to royalty; he was a high-ranking palace official (a Silentiarius) known for his integrity and piety. When Emperor Zeno died in 491 without an heir, the people of Constantinople shouted, “Give us a Christian Emperor! Give us a Roman Emperor!”
Zeno’s widow, Empress Ariadne, chose the sixty-year-old Anastasius to be her husband and the new ruler. His accession was a rare moment of stability in a volatile era.
2. Monetary Reform (The “Follis” Revolution)
Before Anastasius, the bronze coinage of the Empire was a chaotic mess of tiny, worthless coins. In AD 498, he executed the most significant currency reform since Constantine the Great.
- The Large Follis: He introduced large, clearly marked bronze coins (the M, K, and I denominations).
- Stability: This created a reliable “small change” system for the middle and lower classes, facilitating trade.
- The “Byzantine” Marker: Most numismatists consider the start of his reign—specifically this reform—as the official beginning of Byzantine (as opposed to Late Roman) coinage.
3. Financial Genius and the “Golden Age”
Anastasius was a master of the imperial treasury.
- Abolition of the Chrysargyron: He abolished the hated “gold-and-silver” tax on merchants, which was a massive relief to the economy.
- Administrative Efficiency: Despite cutting taxes and fighting expensive wars (against the Isaurians and the Persians), he managed to leave the imperial treasury with a staggering surplus of 320,000 pounds of gold (approx. 23 million solidi).
4. Religious Controversy
His reign was plagued by religious tension. Anastasius leaned toward Miaphysitism (a belief about the nature of Christ), which put him at odds with the Pope in Rome and the orthodox population of Constantinople. This led to several riots and even a serious rebellion by the general Vitalian.
5. Death and Legacy
Anastasius died in 518 at the age of 87, reportedly during a terrifying thunderstorm. Because he had no children, his death paved the way for the rise of Justin I and his nephew, the famous Justinian the Great.
The massive wealth Anastasius left behind was the direct “war chest” that allowed Justinian to later attempt the reconquest of the Western Roman Empire (Italy, Africa, and Spain). Without the fiscal discipline of Anastasius, the “Golden Age of Justinian” would have been impossible.
