The simplest medieval map of the world was the T-O map: a circle divided by a T into the three continents of Asia, Europe and Africa. It is found in many copies of two works written in the early 7th century by Isidore, bishop of Seville: the Etymologies and The Nature of Things. This example is from an 11th-century copy of the Etymologies.
The Etymologies, named after one of its constituent chapters is a compilation of all the knowledge that was available to Isidore, from a wide variety of sources. This manuscript from the Royal manuscripts collection has a 13th- or 14th-century flyleaf inscription stating that it belonged to the priory at Horsham St. Faith, Norfolk.
