200 Korun Chronicler Cosmas

Cosmas of Prague, who died in 1125, wrote the Chronica Bohemorum — the first systematic chronicle of Bohemian history — while serving as Dean of Prague Cathedral. He began the work late in life, completing only three books before his death, and the manuscript was continued by later authors whose additions are often difficult to distinguish from his own. The Czech National Bank has issued commemorative 200 Korun pieces since 1993, typically timed to anniversaries with defined historical anchors; this issue marks the 900th anniversary of Cosmas's death.
