of Iphigenia, Agamemnon's young daughter, as compensation for her slain deer. In most versions, when Iphigenia is led to the altar to be offered as a sacrifice, Artemis pities her and takes her away, leaving another deer in her place. In the war that followed, Artemis along with her twin brother and mother supported the Trojans against the Greeks, and challenged Hera into battle. Artemis was one of the most widely venerated of the Ancient Greek deities, her worship spread throughout ancient Greece, with her multiple temples, altars, shrines, and local veneration found everywhere in the ancient world. Her great temple at Ephesus was one of the Seven Wonders of the Ancient World, before it was burnt to the ground. Artemis' symbols included a bow and arrow, a quiver, and hunting knives, and the deer and the cypress were sacred to her. Diana, her Roman equivalent, was especially worshipped on the Aventine Hill in Rome, near Lake Nemi in the Alban Hills, and in Campania. Etymology The name Artemis (noun, feminine) is of unknown or uncertain etymology, although various sources have been proposed. R. S. P. Beekes suggested that the e/i interchange points to a Pre-Greek origin. Artemis was venerated in Lydia as Artimus. Georgios Babiniotis, while accepting that the etymology is unknown, also states that the name is already attested in Mycenean Greek and is possibly of Pre-Greek origin. The name may be related to Greek árktos "bear" (from PIE *h₂ŕ̥tḱos), supported by the bear cult the goddess had in Attica (Brauronia) and the Neolithic remains at the Arkoudiotissa Cave, as well as the story of Callisto, which was originally about Artemis (Arcadian epithet kallisto); this cult was a survival of very old totemic and shamanistic rituals and formed part of a larger bear cult found further afield in other Indo-European cultures (e.g., Gaulish Artio). It is believed that a precursor of Artemis was worshipped in Minoan Crete as the goddess of mountains and hunting, Britomartis. While connection with Anatolian names has been suggested, the earliest attested forms of the name Artemis are the Mycenaean Greek , a-te-mi-to /Artemitos/ (gen.) and , a-ti-mi-te /Artimitei/ (dat.), written in Linear B at Pylos. According to J. T. Jablonski, the name is also Phrygian and could be "compared with the royal appellation Artemas of Xenophon. Charles Anthon argued that the primitive root of the name is probably of Persian origin from *arta,
