Robert of Ketton

Robert of Ketton, known in Latin as Rodbertus Ketenensis, was an English astronomer, translator, priest and diplomat active in Spain. He translated several works of Arabic into Latin, including the first translation of the Quran into any Western language. Between 1144 and 1157 he held an archdeaconry in the diocese of Pamplona. In the past he has been confounded with Robert of Chester, another English translator active in Spain in the mid-twelfth century; and at least one modern scholar believes they are the same person.
