Meropis is situated beyond the world-ocean (Oceanus). Its inhabitants, the Méropes, are twice as tall as other human beings and live twice as long. Theopompos describes three cities in Meropis: Anostos (Ἄνοστος, “Place of No Return”), Eusebes (Εὐσεβής, “Pious-Town”) and Machimos (Μάχιμος, “Fighting-Town”). While the inhabitants of Eusebes are living in opulence getting neither hungry nor sick, the inhabitants of Machimos are in fact born with weapons and carry on wars steadily. The third city, Anostos, is situated on the outermost border of Meropis. It resembles a yawning abyss, does not have day or night, and is covered by cloudy, red fumes.
