The ancient Hellenes didn't believed in idolatry, the had a complicated religion full of Gods. Using the oracle of Trophonios in Boetia as an example we will see how this worked every time.
There is a several amount of people even in Hellas who believe that ancient Hellenes worshipped statues, so they call them eidololatres and the phenomenon idolatry. In ancient hellenic religion people believed in Gods and Goddesses, energies of the universe, angels, daimones (daimons). The gave to those energies different forms according to their vision or experience. Those forms were the statues. So ancient Hellenes never woshipped statues but the idea behind the statue, the idea that the statue represented.
