Mappa mundi is a general term used to describe Medieval European maps of the world. These maps ranged in size and complexity from simple schematic maps an inch or less across, to elaborate wall maps, the largest of which was 11 ft. (3.5 m.) in diameter. The term derives from the Medieval Latin words mappa (cloth or chart) and mundi (of the world). Approximately 1,100 mappae mundi are known to have survived from the Middle Ages. Of these, some 900 are found illustrating manuscripts and the remainder exist as stand-alone documents.
To modern eyes, mappae mundi can look superficially primitive and inaccurate. However, mappae mundi were never meant to be used as navigational charts and they make no pretense of showing land and water proportionately. Rather, mappae mundi were schematic and were meant to illustrate different principles. The simplest mappae mundi were diagrams meant to preserve and illustrate classical learning easily.
