Greek mythology is largely made up of stories about gods and goddesses, but it must not be read as a kind of Greek Bible, an account of the Greek religion.
According to the most modern idea, a real myth has nothing to do with religion. It is an explanation of something in nature; how, for instance, any and everything in the universe came into existence: men, animals, this or that tree or flower, the sun, the moon, the stars, storms, eruptions, earthquakes, all that is and all that happens. Thunder and lightning ale caused when Zeus hurls his thunderbolt. A volcano erupts because a terrible creature is imprisoned in the mountain and every now and then struggles to get free. The Dipper (大熊星座), the constellation (星座) called also the Great Bear, does not set below the horizon because a goddess once was angry at it and decreed (命令) that it should never sink into the sea. Myths ale early science, the result of men’s first trying to explain what they saw around them.
