Artemis vs Diana

Is Diana the same as Artemis? In myth, yes — Ovid's Diana turns Actaeon into a stag exactly as Apollodorus's Artemis does, and both are Leto's daughter, huntress and virgin. In cult, no — Diana had a temple on the Aventine built by Servius Tullius with the Latin League, and a grove at Aricia where horses were banned; and Latin poets fold Trivia and Luna into her name.
