Quick Summary

Marianus Scotus, an Irish monk and chronicler, wrote the Chronicon between 1028 and 1082. This universal history spans from the creation of the world to 1082.1

The Chronicon is notable for disputing the chronology of the Paschal calendar established by Dionysius Exiguus, asserting that Christ's birth was dated 22 years too early. While Marianus Scotus's chronological system did not replace the Paschal calendar, his work is valuable for its historical account and insights into the Irish monastic movement in Germany during the 10th and 11th centuries. The Chronicon was popular among medieval chroniclers due to its reliance on numerous ancient and early medieval scholarly sources.1
