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.
