How We Drew the World

Until the 15th century, European ideas about the world were strongly shaped by inherited traditions. Medieval maps often resembled illuminated manuscripts more than navigational tools. On maps known as mappae mundi, Jerusalem was placed at the centre of the world, Paradise at the top, and the edges of the known world were filled with mythical creatures and symbols of the unknown.

A turning point came during the Renaissance, when Ptolemy’s 2nd-century Geography was rediscovered. Claudius Ptolemy introduced a system of meridians and parallels, giving cartography a mathematical and scientific foundation. His image of the world nevertheless contained many inaccuracies: he believed the Earth to be smaller than it is, knew nothing of the American continents, depicted the Indian Ocean as an enclosed sea, and joined Africa to an imagined southern landmass.

THE AGE OF GREAT CORRECTIONS

The voyages of Christopher Columbus, Ferdinand Magellan and Vasco da Gama brought discoveries that fundamentally changed the established image of the world. The period from 1500 to 1600 was one of the most exciting in the history of cartography—an age of constant revision, correction and new discoveries.

THE TURNING POINT AROUND 1600

Around 1600, the centre of European cartography shifted to Amsterdam, and the Netherlands became the world’s leading centre for printing and trading maps. Accurate maps were an important source of political, military and economic power.

FROM SEA MONSTERS TO SCIENCE

Maps made before 1600 often featured sea monsters devouring ships in unknown waters. They were not merely decorative, but symbols of gaps in knowledge and fear of the unknown. As the 17th century approached, such images gradually disappeared and were replaced by more precise figures, soundings, coordinates and astronomical measurements.
