Argos was a very important and the second oldest city of Ancient Greece, located in the northeast part of the Peloponnese, close to Nafplion. Argos was founded by Phoroneus, but the mythological founder of Argos was Argos, son of Zeus and Niobe, the first mortal lover of Zeus.
Argos was a wealthy, rich watered region so it inevitably became attractive for two Olympian gods: Hera, the beautiful wife of Zeus, and Poseidon, the moody god of the Seas, who was charmed by the city's calm waters.
At one point, the dispute became so strong that the Rivers, who were the powers of the city, had to sit on a committee and take a fair decision. After long-run negotiations, the Rivers finally vote for Hera. Poseidon was full of rage with their decision- after all, they were his cousins!- so he went on to dry out the once rich-watered land of Argos.
The Heraeum of Argos was a famous sanctuary of Hera, built by the architect Eupoloemos. The most important part of the sanctuary was a chryselephantine cult statue of Hera sitting on a throne . The statue was created around around 420 BC. by Polykleitos, a famous scupltor of Argos.
The brother of Polykleitos, Naukydes later on also created a chryselephantine cult statue of Hebe, the cup-bearer of the gods, and located it next to the statue of Hera. Unfortunately, none of the statues were preserved.
