Bartholomaeus Anglicus

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.

The work De proprietatibus rerum was written at the school of Magdeburg in Saxonia and intended for the use of students and the general public.

[1] Bartholomew carefully notes the sources for the material included, although, at present, it is sometimes impossible to identify or locate some of them.

This appointment included Poland where he resolved a dispute between Duke Boleslaw and the Cathedral Chapter at Kraków.
