Bartholomaeus Anglicus (before 1203–1272),[1] also known as Bartholomew the Englishman and Berthelet, was an early 13th-century Scholastic of Paris, a member of the Franciscan order. He was the author of the compendium De proprietatibus rerum ("On the Properties of Things"),[2] dated c.1240, an early forerunner of the encyclopedia and a widely cited book in the Middle Ages.[3] Bartholomew also held senior positions within the church and was appointed Bishop of Łuków in what is now Poland, although he was not consecrated to that position.[1]
