Read the passage from Heracles.Ancient peoples believed in a pantheon of gods. To the ancient Greeks, the gods possessed human characteristics, including their weaknesses, such as vanity, greed, jealousy, vengefulness, and cruelty. In their stories, there was regular interaction between gods and humans, as well as demigods, who were the offspring of a union between a god and a mortal. Thus, many myths have to do with the struggle between them.
