So, what did the Argives believe in?

          The citizens of Argos believed in the great, queen of the gods, Hera. Although they believed in the other Greek gods, Hera was their focus.
          Not only was Hera the queen of the gods, but she was also the goddess of marriage. She was Zeus's wife. Or one of his wives. Because Zeus would get married to other people behind Hera's back, Hera would get very jealous and would release her wrath on all of Zeus's wives and children. Sometimes her plans didn't work out. They would actually backfire. One of Hera's well known stories involved her trustful guard, Argus, who had one hundred eyes, Hermes, the messenger god, Zeus, king of the gods, and Io, one of Zeus's wives. The story went like this:
      One day, Hera was getting a little suspicious about Zeus. He had been out of Mount Olympus with the humans for a while. Hera decided to go down and see what her husband was up to. As she was on her way down, she saw a dark cloud that seemed out of place. She went to go see why it was there. Zeus was on that cloud with his new wife. He didn't want Hera to see this so he quickly turned his wife, Io, into a snowy white cow. Hera knew that Zeus had turned Io into the cow, so she begged Zeus to give her the cow, pretending she had no idea that it was one of his wives. He finally gave in and gave Hera the cow regretfully. Hera tied Io to one of her beautiful trees and sent her trustful guard to watch her. Argus had one hundred eyes and only closed half of them to sleep. Zeus was getting a little worried, and sent Hermes, the messenger god to get Io. Hermes disguised himself as a shepherd. He walked up to Argus and played music for him on his lyre. Hermes started to tell Argus a long story that had no beginning and no end. Argus closed all of his eyes one by one. Argus was literally board to death. Hermes let Io go. Io quickly ran to her father. Her father couldn't tell who the cow was. Io scratched her name into the dirt and her father understood. Io's father was the river-god Inachos. He was so mad that he ran to Zeus. Zeus had to use his mighty thunder bolts to get rid of him. Hera was so mad that Argus had died and that Io escaped. She sent a gadfly to chase and sting Io, the cow. Hera didn't want Argus to be forgotten, so she took his one hundred eyes and delicately put them on her favorite bird's tail, the peacock Io was chased around Greece, until she went to Egypt. There, the Egyptian praised her and she became an Egyptian goddess. Hera made Zeus promise that he would never turn Io into a human. Zeus also had to promise never to see Io again.
                    That was just one of many stories that Hera was trying to get rid of Zeus's wives and children.
