Greco-Roman mythology

Greco-Roman mythology refers to the combined mythological traditions of ancient Greece and Rome, treated as a unified system.

The Romans adopted and adapted Greek gods, heroes, and stories—Zeus became Jupiter, Aphrodite became Venus, Heracles became Hercules.

The term recognizes that these traditions, while distinct in origin, merged so thoroughly that they're often studied together: a course in Greco-Roman mythology, Greco-Roman deities.
