CERCOPES. These were two brothers living upon the earth who practised every kind of knavery. They were called Cercopes1 because of their cunning doings: one of them was named Passalus and the other Acmon. Their mother, a daughter of Memnon, seeing their tricks, told them to keep clear of Black-bottom, that is, of Heracles. These Cercopes were sons of Theia and Ocean, and are said to have been turned to stone for trying to deceive Zeus.
