Classical mythology, also known as Greco-Roman mythology or Greek and Roman mythology, is the collective body and study of myths from the ancient Greeks and ancient Romans. Mythology, along with philosophy and political thought, is one of the major survivals of classical antiquity throughout later, including modern, Western culture. The Greek word mythos refers to the spoken word or speech, but it also denotes a tale, story or narrative.
As late as the Roman conquest of Greece during the last two centuries Before the Common Era and for centuries afterwards, the Romans, who already had gods of their own, adopted many mythic narratives directly from the Greeks while preserving their own Roman (Latin) names for the gods. As a result, the actions of many Roman and Greek deities became equivalent in storytelling and literature in modern Western culture. For example, the Roman sky god Jupiter or Jove became equated with his Greek counterpart Zeus; the Roman fertility goddess Venus with the Greek goddess Aphrodite; and the Roman sea god Neptune with the Greek god Poseidon.
