Hera is known for her jealousy; even Zeus, commonly portrayed as fearless, feared her rages. Zeus fell in love with Hera, but she refused his first marriage proposal. Zeus then preyed on her empathy for animals and other beings, created a thunderstorm and transformed himself into a little cuckoo. As a cuckoo, Zeus pretended to be in distress outside her window. Hera, feeling pity towards the bird brought it inside and held it to her breast to warm it. Zeus then transformed back into himself and raped her. Hera, ashamed of being exploited, agreed to marriage with Zeus. All of nature burst into bloom for their wedding and many gifts were exchanged.
