Artemis was one of the most widely venerated of the Ancient Greek deities. Her Roman equivalent is Diana. Some scholars believe that the name and indeed the goddess herself was originally pre-Greek. Homer refers to her as Artemis Agrotera, Potnia Theron: "Artemis of the wildland, Mistress of Animals". In the classical period of Greek mythology, Artemis (Greek: (nominative) Ἄρτεμις, (genitive) Ἀρτέμιδος) was often described as the daughter of Zeus and Leto, and the twin sister of Apollo. She was the Hellenic goddess of the hunt, wild animals, wilderness, childbirth, virginity and young girls, bringing and relieving disease in women; she often was depicted as a huntress carrying a bow and arrows. The deer and the cypress were sacred to her. In later Hellenistic times, she even assumed the ancient role of Eileithyia in aiding childbirth.
Various conflicting accounts are given in Classical Greek mythology of the birth of Artemis and her twin brother, Apollo. All accounts agree, however, that she was the daughter of Zeus and Leto and that she was the twin sister of Apollo.
An account by Callimachus has it that Hera forbade Leto to give birth on either terra firma (the mainland) or on an island. Hera was angry with Zeus, her husband, because he had impregnated Leto. But the island of Delos (or Ortygia in the Homeric Hymn to Artemis) disobeyed Hera, and Leto gave birth there.
In ancient Cretan history Leto was worshipped at Phaistos and in Cretan mythology Leto gave birth to Apollo and Artemis at the islands known today as the Paximadia.
A scholium of Servius on Aeneid iii. 72 accounts for the island's archaic name Ortygia by asserting that Zeus transformed Leto into a quail (ortux) in order to prevent Hera from finding out his infidelity, and Kenneth McLeish suggested further that in quail form Leto would have given birth with as few birth-pains as a mother quail suffers when it lays an egg.
The myths also differ as to whether Artemis was born first, or Apollo. Most stories depict Artemis as born first, becoming her mother's mid-wife upon the birth of her brother Apollo.
The childhood of Artemis is not fully related in any surviving myth. The Iliad reduced the figure of the dread goddess to that of a girl, who, having been thrashed by Hera, climbs weeping into the lap of Zeus. A poem of Callimachus to the goddess "who amuses herself on mountains with archery" imagines some charming vignettes: according to Callimachus, at three years old, Artemis, while sitting on the knee of her father, Zeus, asked him to grant her six wishes: to remain always a virgin; to have many names to set her apart from her brother Apollo; to be the Phaesporia or Light Bringer; to have a bow and arrow and a knee-length tunic so that she could hunt; to have sixty "daughters of Okeanos", all nine years of age, to be her choir; and for twenty Amnisides Nymphs as handmaidens to watch her dogs and bow while she rested. She wished for no city dedicated to her, but to rule the mountains, and for the ability to help women in the pains of childbirth.
Artemis believed that she had been chosen by the Fates to be a midwife, particularly since she had assisted her mother in the delivery of her twin brother, Apollo. All of her companions remained virgins, and Artemis closely guarded her own chastity. Her symbols included the golden bow and arrow, the hunting dog, the stag, and the moon. Callimachus tells how Artemis spent her girlhood seeking out the things that she would need to be a huntress, how she obtained her bow and arrows from the isle of Lipara, where Hephaestus and the Cyclops worked. Okeanus' daughters were filled with fear, but the young Artemis bravely approached and asked for bow and arrows. Callimachus then tells how Artemis visited Pan, the god of the forest, who gave her seven bitches and six dogs. She then captured six golden-horned deer to pull her chariot. Artemis practiced with her bow first by shooting at trees and then at wild beasts.
As a young virgin, Artemis had interested many gods and men, but none of them successfully won her heart, except her hunting companion Orion, who was then accidentally killed either by the goddess herself or by Gaia.
Alpheus, a river god, was in love with Artemis, but he realized that nothing he could do would win her heart. So he decided to capture her. Artemis who was with her companions at Letrenoi, went to Alpheus, but suspicious of his motives, she covered her face with mud so the river god would not recognize her. Another story involving the god is the story where he tried to rape Artemis' attendant Arethusa. The goddess felt pity for her and saved her by transforming Arethusa into a spring in Artemis' temple, Artemis Alphaea in Letrini, where the goddess and her attendant drink.
Bouphagos, the son of the Titan Iapetos, saw Artemis and had a thought of raping her. Detecting his sinful thoughts Artemis struck him at Mount Pholoe.
Sipriotes was a boy who, either because he accidentally saw Artemis bathing or attempted to rape her, was turned into a girl by the goddess.
