Greek mythology mainly includes two parts: legends of gods and legends of heroes. In the legends of gods, gods have distinct personalities and have the same joys and sorrows as ordinary people. The protagonists of heroic legends are mostly half-gods and half-human heroes. They have extraordinary physical strength and bravery, embodying the heroic spirit and tenacious will of mankind to conquer nature, and have become the embodiment of the collective strength and wisdom of the ancient people.
