A picture of history, not a route planner
The Latin phrase mappa mundi means roughly “cloth of the world,” and it was applied to many world maps of the Middle Ages. Looking at one with modern eyes, it is easy to think the makers were simply bad at geography. That reading misses the point. A mappa mundi was not meant for finding the way from one town to the next. It combined geography, scripture, ancient learning and history on a single sheet, a kind of encyclopedia in picture form. Sailors used something else entirely, practical sea charts drawn by specialist chart makers.
The T-O layout
The simplest form is the T-O map. A circle, the “O,” represents the known world surrounded by ocean. Inside, a “T” divides it into three parts. The top, usually the east, holds Asia, the largest. The lower left and right hold Europe and Africa, separated by the Mediterranean, with rivers such as the Don and the Nile forming the arms of the T. This layout reflects an old belief that the three continents were allotted to the three sons of Noah, and it gave a compact way to illustrate that idea.
Orientation was different from ours. East, the direction of the rising sun and of Paradise, was at the top, which is where the word “orient” comes from. That is why the maps seem turned sideways to modern viewers.
Jerusalem at the center
Many of the large maps placed Jerusalem at or near the middle. This was not an error about distance. It was a statement about meaning. Jerusalem was the city of Christ’s death and resurrection, and many writers regarded it as the spiritual center of the world, a view supported by biblical passages. For a map whose purpose was to show how the world fit into a sacred story, the center was the obvious place for the city. The belief also shaped the holy places visited by pilgrims, and Holy Land pilgrimage was one of the main reasons ordinary people thought about distant geography at all.
Eden and the edge of the world
At the top of many maps, often in the far east, a small enclosure represents the Garden of Eden, sometimes with the rivers said in Genesis to flow from it. Maps could also show Adam and Eve, the Tower of Babel, Noah’s Ark or the crossing of the Red Sea. Reading from top to bottom, then, a viewer moved from the beginning of human history in the east toward the present in the west. Some maps place a figure of Christ above the circle, presiding over the world, or a scene of the Last Judgment at the edge. In this scheme the map holds the whole span of time, not just space.
Far lands, wonders and legendary peoples
The edges of these maps are populated. Writers inherited ancient and early medieval accounts of distant regions, and mapmakers copied them. Common features include:
- strange peoples, such as figures with unusual faces or bodies, often drawn from classical writers and later compilations
- real and imagined animals, from elephants to dragons or the mythical unicorn
- legendary kingdoms, including the realm of a priest-king in the east that circulated in rumor
- islands in the western ocean, such as places from Irish voyage stories
Mapmakers did not necessarily believe each detail. Some of the creatures stood for the diversity of God’s creation, and others were included because an authority recorded them. The accompanying text might warn that something was reported rather than seen. Accounts by travelers such as Marco Polo gradually added firsthand information, but the older traditions persisted alongside it.
Great surviving examples
Only a few large maps survive. The best known is a very large map on a single piece of vellum, now in Hereford Cathedral, usually dated to about 1300. It is richly decorated and holds hundreds of entries, from towns and rivers to biblical scenes and wonders. Another famous map, from Ebstorf in Germany, was destroyed in the Second World War and is known mostly from copies and photographs. Smaller world maps appear in manuscripts of chronicles, encyclopedias and commentaries on scripture, often drawn by a monk or cleric illustrating the text.
Because few survive and many were copied, historians discuss how much these maps tell us about a typical reader’s understanding of the world, as opposed to the interests of a scholarly few. They were probably displayed or studied in settings where learned and religious audiences gathered.
How to read one
A mappa mundi is best read as an argument about the world’s order. Position expressed importance, so Jerusalem is central, Paradise is at the top, and the known peoples of the earth are arranged around them. Cities and rivers are drawn if they mattered to scripture, history or learning, not because they were on a road. Later maps, particularly those influenced by new sea charts and by trade with Asia, began to blend this tradition with more measured geography, but the older picture of a sacred world remained powerful for centuries.
