The writings of ancient historians and geographers sometimes mention animals that are impossible or almost impossible to identify. These are not necessarily representatives of a fantastic fauna, like the winged snakes of Herodotus, guarding trees that give incense. For example, the same Herodotus describes some real rodents found in Libya: “The mice there are of three breeds: some are called bipeds, others are called “zegeria” (Libyan word, in Hellenic means hill), the third - hedgehogs... This is how many animals are found in the land of the Libyan nomads..." If the definition of two-legged mice and hedgehog mice does not cause difficulties, then find out what zegeria mice are very problematic...
