In Greek mythology, the beautiful goddess Hera was queen of the Greek gods and the wife of Zeus, the king. Hera was goddess of marriage and childbirth. Since Hera's husband was Zeus, king not only of gods, but of philanderers, Hera spent a lot of time in Greek mythology angry with Zeus. So Hera is described as jealous and quarrelsome.
Zeus' continuous womanizing had driven Hera to the edge.
