Ingeld or Ingjaldr was a legendary warrior who appears in early English and Norse legends. Ingeld was so well known that, in 797, Alcuin wrote a letter to Bishop Higbald of Lindisfarne questioning the monks' interest in heroic legends with: 'Quid enim Hinieldus cum Christo?' - What has Ingeld to do with Christ?

Alcuin of York – also called Ealhwine, Alhwin, or Alchoin – was a scholar, clergyman, poet, and teacher from York, Northumbria. He was born around 735 and became the student of Archbishop Ecgbert at York. At the invitation of Charlemagne, he became a leading scholar and teacher at the Carolingian court, where he remained a figure in the 780s and 790s. Before that, he was also a court chancellor in Aachen. "The most learned man anywhere to be found", according to Einhard's Life of Charlemagne, he is considered among the most important intellectual architects of the Carolingian Renaissance. Among his pupils were many of the dominant intellectuals of the Carolingian era.
