Mythology is the body of myths and teachings that belong to the ancient people, concerning their gods and heroes, the nature of the world, and the origins and significance of their own cult and ritual practices. It was a part of the religion in ancient Greece and is part of religion in modern Greece and around the world, known as Hellenismos.

Modern scholars refer to and study the myths in an attempt to throw light on the religious and political institutions of Ancient Greece and its civilization, and to gain understanding of the nature of myth-making itself.
