See also: Israel the GrammarianIsrael the Grammarian (fl. c.900-c.970) – Tenth-century teacher, scholar and poet. He had been a student of John Scottus Eriugena, spent time at the court of King Æthelstan, found a new patron in Rotbert, archbishop of Trier, and became tutor to Bruno, brother of Otto I and later archbishop of Cologne. Breton, Welsh and Irish origins have been variously ascribed to him, with the Breton hypothesis currently finding most favour in scholarship.
