Sedulius Scottus
Irish teacher, Latin grammarian and scriptural commentator

Sedulius Scotus or Scottus (fl. 840–860) was an Irish monk, teacher, Latin grammarian, and scriptural commentator who lived in the 9th century. During the reign of the Emperor Lothair (840–855), he was one of a colony of Irish teachers at Liège. Sedulius is sometimes called Sedulius the Younger, to distinguish him from Coelius Sedulius (a 5th-century poet). The usual Irish form of the name is Siadhal, but he appears to have been called Suadbar. It is quite probable that towards the end of his days he went to Milan, following the example of his countryman Dungal, who established a school at Pavia. When and where he died is unknown.
Life
In search of warmer land to accommodate their growing population, the Norse Vikings made their way into Ireland during the mid-ninth century. Those already occupying the land, Irish monks, were driven out of their monasteries by force. A monk by the name of Sedulius Scottus was among them, and his search for refuge led him to the city of Liège.
