Thierry of Chartres

Thierry of Chartres (Theodoricus Chartrensis) or Theodoric the Breton (Theodericus Brito) (died before 1155,^[1] probably 1150^[2]) was a twelfth-century philosopher working at Chartres and Paris, France.

The cathedral school at Chartres promoted scholarship before the first university was founded in France. Thierry was a major figure in twelfth-century philosophy and learning, and, like many twelfth-century scholars, is notable for his embrace of Plato's Timaeus and his application of philosophy to theological issues.^[3] Some modern scholars believed Thierry to have been a brother of Bernard of Chartres who had founded the school of Chartres, but later research has shown that this is unlikely.^[4]

Thierry became chancellor of Chartres after his predecessor, Gilbert of Poitiers, returned to his native city in 1141. John of Salisbury,^[5] Herman of Carinthia, and Clarembald of Arras were among Thierry's students.^[6]
