Hera was the Greek god of marriage. She was also the queen of the Greek gods. Hera hated the Greek hero Hercules. Hercules was the son of Zeus and a mortal woman. Hera attempted to kill Hercules on several occasions. In contrast, Hera assisted Jason with his quest to retrieve the golden fleece.
The worship of Hera may be much older than her role in Greek Mythology. It has been written that some of the first deities were female, and that worship of Hera or a similar god stretched back to before written word.
