Greek mythology

Hermes was the messenger of the gods. He was a deity of wealth, god of trade and travelers, of commerce, manual skill, oratory and eloquence, of thieves and of the wind.


The discovery of (69230) Hermes clashed with the transition from silent movies to sound movies, which resulted in changes in actors selection, since many actors of success in silent film, did not have an appropriate voice for sound movies.

During its rediscovery (August 2003), appeared the application Skipe, that allowed to talk on the phone, free of charge, via the internet with any part of the world.


(69230) Hermes is related with the modulation of voice and expressiveness through comunications by radio, specially the military type.

The ninth labor of Heracles was to obtain the Girdle of Hippolyte (sister of Antiope), which his father (Ares, the god of war) had given to her. Heracles kidnapped Antiope and demanded the Girdle of Hippolyte as exchange.
