To which mythological figure does the constellation Leo refer?

The correct association of the constellation Leo is with the mythological figure of Hercules. In Greek mythology, Leo is often identified with the Nemean Lion, which was the first labor of Hercules. According to the myth, Hercules was tasked with slaying the invulnerable lion that terrorized the region of Nemea. After defeating the lion, he wore its skin as armor, which ultimately became a symbol of his strength and was later immortalized in the stars as the constellation Leo.

While Apollo, Orion, and Perseus are important figures in mythology, they are not directly linked to the constellation Leo. Apollo is more commonly associated with the Sun and various aspects of culture and arts, Orion represents a hunter in mythology, while Perseus is known for his adventures, including slaying Medusa. Each of these characters has their own respective constellations and stories within Greek mythology that do not overlap with the tale of the Nemean Lion and Hercules.
