When did revenge begin in Greek mythology?

Answer 1

Revenge began when the gods were angry with the race of men. Zeus decided to place the first woman down to Earth. Her name was Pandora. She was beautiful and kind but the seed of curiosity was placed in her heart. They fixed her up and put her down to Earth. Then, the gods gave her a box and told her never to look inside of it. She lived many years in peace until her curiosity got the best of her and she took a little peek in the jar. All the misfortunes that we have today got unleashed except for the one misfortune, hope. Without hope, mankind would have been destroyed but still, mischief, jealousy, revenge and many other terrible things got unleashed into the world because of Pandora's curiosity.
