Explanation: At the beginning of "The Odyssey" by Homer, Zeus is gathered with all the gods at Mount Olympus. He says that men often blame the gods for their misfortunes. But, it is they who bring their own sorrows upon themselves. He then tells the story of Aegisthus. Aegisthus was the lover of Clytemnestra. Although being warned by the gods, he killed her husband. When Clytemnestra's son came of age, he killed both Aegisthus and her.
