Diana. An ancient Italian divinity, whom the Romans identified with the Greek Artemis. Her worship is said to have been introduced at Rome by Servius Tullius, who dedicated a temple to her on the Aventine. At Rome Diana was the goddess of light. She was a daughter of Jupiter, and was born of Latona, or Leto, on the island Delos, at the same time with Apollo. As in Apollo the sun was deified and adored; so was the moon in Diana.
