Ancient and Medieval World Maps: When Cartography Was Cosmology

Before cartography became a science, it was a theology. The medieval mappa mundi — the world map as understood and depicted by European Christian scholars from the 7th through the 15th centuries — was not primarily a navigation tool. It was a cosmological statement: an image of the world as God had ordered it, with Jerusalem at the center, the Garden of Eden at the top, the known continents arranged according to the sons of Noah (Asia/Shem, Africa/Ham, Europe/Japheth), and the strange peoples of the earth's margins (the Cynocephali, the Sciapods, the Blemmyae) marking the boundaries of the known against the unknown. The famous Hereford Mappa Mundi (c. 1300 CE) and the Ebstorf Map (c. 1234 CE, destroyed in World War II) were not errors corrected by subsequent discovery. They were different kinds of truth — theological and symbolic maps of a universe in which geography, history, mythology, and salvation history occupied the same spatial plane. The Fra Mauro Map of 1450 marks the transition: still adorned with marvels and theological symbols, but already oriented toward empirical accuracy, already receiving the Portuguese coastal discoveries that would render the medieval world-picture obsolete.

Hereford Mappa Mundi (c. 1300 CE) — the largest surviving medieval world map, 1.58 × 1.33 meters, drawn on a single calf skin; Jerusalem at the center, the Garden of Eden at the top, Christ presiding over the Last Judgment above all; the map is simultaneously a geography, a history of the world from Creation to the present, and an instruction in salvation

T-O Map — the simplest form of medieval world cartography; the O is the ocean surrounding the world, the T divides the three known continents: Asia (upper half), Africa (lower right), Europe (lower left); the T's crossbar is the Mediterranean Sea and the Don River, the vertical bar is the Nile and the Mediterranean; Jerusalem is at the center, the east at the top

Ebstorf Map (c. 1234 CE, reconstruction) — the largest medieval world map ever made, 3.57 × 3.56 meters (destroyed in 1943 during World War II); Christ's head appears at the top, his hands on the sides, his feet at the bottom — the world is Christ's body; the map was made by Benedictine nuns at Ebstorf Monastery as a theological meditation on the world as the body of God

Fra Mauro World Map (c. 1450 CE) — made by the Venetian monk Fra Mauro at the monastery of San Michele, Venice; oriented with south at the top (following Islamic cartographic tradition); the most geographically accurate pre-Ptolemaic world map in the Western tradition; Fra Mauro incorporated information from Marco Polo's travels, Portuguese exploration, and Islamic geography

Fra Mauro Map compared to satellite imagery — rotated to north-up orientation, the Fra Mauro map's coastal geography is remarkably accurate for its period; Fra Mauro captured the outline of sub-Saharan Africa (the Portuguese had just rounded Cape Bojador) before Vasco da Gama completed the route to India; the map is a snapshot of the moment when empirical discovery began to outpace theological cartography

Fra Mauro Map, 1806 copy — made for the British Library; the original map is preserved in the Biblioteca Nazionale Marciana in Venice; Fra Mauro's map is adorned throughout with thumbnail illustrations of cities, mountains, and rivers, and with text descriptions drawing on classical, Arabic, and contemporary sources; it is as much an encyclopedia as a map
