Ancient world map Universalis tabvula ivxta Pteolemaeum by Petrus Bertius and Gerhard Mercator

Universalis Tabvla Ivxta Ptolemaeum is a historical world map associated with the cartographic traditions of Petrus Bertius and Gerhard Mercator. Produced in the early seventeenth century from the Ptolemaic geographic model, the map presents the world according to the teachings of the ancient geographer Claudius Ptolemy rather than contemporary discoveries. Engraved in a refined Renaissance style, it features classical place names, an enclosed Indian Ocean, and other geographical concepts inherited from antiquity, illustrating how scholars compared ancient and modern views of the world.

Petrus Bertius (1565–1629) was a Dutch scholar, historian, and mapmaker known for publishing atlases and educational geographic works. Gerhard Mercator (1512–1594) revolutionized cartography through the Mercator projection and his influential atlases, which shaped European mapmaking for centuries. Together, their names represent the blending of classical geographic scholarship and Renaissance scientific cartography that defined the golden age of map production.
