Meropis

Although Atlantis was incredibly big by Plato's account, Theopompus describes Meropis as even bigger, to make it completely absurd.

Also, while the invading Atlanteans were beaten by Athens due to its perfect society, the Méropes (Μέροπες)—attacking with an army of ten million soldiers—attempt to conquer Hyperborea, but return in disgrace after realizing that the Hyperboreans were the luckiest people on earth and not worth looting.

[citation needed] Meropis is also one of historical names of the Greek island of Kos, ruled by Merops.

Theopompos describes three cities in Meropis: Anostos (Ἄνοστος, "Place of No Return"), Eusebes (Εὐσεβής, "Pious-Town") and Machimos (Μάχιμος, "Fighting-Town").

It resembles a yawning abyss, does not have day or night, and is covered by cloudy, red fumes.
