Cercopes

In Greek mythology, the Cercopes (Greek: Κέρκωπες, plural of Κέρκωψ, from κέρκος (n.) kerkos "tail") were mischievous forest creatures who lived in Thermopylae or on Euboea but roamed the world and might turn up anywhere mischief was afoot. They were two brothers, but their names are given variously, Passalus and Acmon, Basalas and Achemon, Olus and Eurybatus, or Sillus and Triballus, depending on the context, but usually known as sons of Theia and Oceanus, thus ancient spirits.

They were proverbial as liars, cheats, and accomplished knaves. They once stole Heracles' weapons, during the time he was the penitent servant of Omphale in Lydia. He seized and bound them at Ephesus and punished them by tying them to a shoulder pole he slung over his shoulder with their faces pointing downwards, the only way they appear on Greek vases. The sight of Heracles' dark-tanned posterior set them both to laughing; when Heracles demanded to know what they were laughing at and they told him, he joined them in their laughter and let them go. This particular myth is depicted on a metope at Temple C at Selinus. In another myth, designed to explain their name ("tail-men" in Greek), Zeus changed the Cercopes into monkeys (from this we have the genus Cercopithecus, identified as the genus of monkeys depicted in Minoan frescoes). In a myth alluded to in a fragment of Pherecydes, Zeus turned one of them to stone for trying to deceive even him; the stone was shown to visitors to Thermopylae. The other one was later transformed into a carved wooden piece carrying the burden of a golden challis filled with a trance-inducing golden potion ("ale" or sometimes referred to as "beer" in contemporary Britain. However, in modern times the challis is said to have been lost.
