Bartholomeus Anglicus (before 1203 – 1272), 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"), dated at 1240, an early forerunner of the encyclopedia and one of the most popular books in medieval times. Bartholomew also held senior positions within the church and was appointed Bishop of Łuków although he was not consecrated to that position.
