Ancient map of Italy. Italia antiqva by Philipp Cluver, Abraham Ortelius, and Petrus Bertius

Italia Antiqua is a historical map depicting ancient Italy, based on classical geographic knowledge and scholarly research. Associated with the works of Philipp Cluver, Abraham Ortelius, and Petrus Bertius, the map illustrates the Italian peninsula as it was understood in antiquity, showing Roman regions, ancient cities, rivers, and mountain ranges. Engraved in the refined cartographic style of the sixteenth and seventeenth centuries, it served as an important reference for students of classical history and geography.

Philipp Cluver (1580–1622) is often regarded as a founder of historical geography, while Abraham Ortelius (1527–1598) revolutionized map publishing through his influential atlas Theatrum Orbis Terrarum. Petrus Bertius (1565–1629) further expanded the tradition of educational and historical cartography. Together, their scholarship helped shape European understanding of the ancient world, blending classical texts with the evolving art of mapmaking.
