Geography

Book • 150
Ptolemy's 'Geography' is a seminal work that includes a treatise on cartography, a gazetteer with longitude and latitude coordinates for approximately 8,000 locations, and instructions for creating maps of the known world.

The work is divided into eight books, covering methods of cartography, a gazetteer of the world known to the ancient Romans, and detailed instructions for map projections.

Ptolemy's innovations included the use of a grid system to plot latitude and longitude and the development of map projections that anticipated later cartographic techniques.

Despite some inaccuracies, such as miscalculating the Earth's size, the work was highly influential in both the Islamic world and Renaissance Europe.
