Mythology is a field of study that seeks to explain the natural world and human experiences through stories about gods, goddesses, heroes and rituals. Some key questions mythology seeks to address are: who are we, how was the world made, what happens after death, and what is the proper way to conduct religious ceremonies. The study of mythology involves inquiries into Greek and Roman gods and goddesses like Zeus, Poseidon, Hades, Hera and others; their associated symbols and domains of power over natural forces, human activities and institutions.
