in his book In the World Interior of Capital (2014, original German: Im Weltinnenraum des Kapitals, 2005). Sloterdijk takes these terms directly from the work of Eric Voegelin, specifically from Order and History vol. 4, The Ecumenic Age (1974), which he quotes. Science fiction writer Ursula Le Guin derived the term Ekumen in her Hainish Cycle from this Greek term. Note that the term "ecumene" can differ depending on the viewpoint from which it is perceived: for example, the Ancient Babylonians and the Ancient Greeks would each have known a different area of the world (though their worlds may have overlapped).

Cartography The term is used in cartography and historical cartography to describe a type of map, namely the symbolic, schematic world maps made in late antiquity and the Middle Ages.
