Artemis was the daughter of Leto and Zeus, and the twin of Apollo. She is the goddess of the wilderness, the hunt and wild animals, and fertility. She is the helpers of midwives as a goddess of birth.
In one legend, Artemis was born one day before her brother Apollo. Her mother gave birth to her on the island of Ortygia, then, almost immediately after her birth, she helped her mother to cross the straits over to Delos, where she then delivered Apollo. This was the beginning of her role as guardian of young children and patron of women in childbirth. Being a goddess of contradictions, she was the protectors of women in labor, but it was said that the arrows of Artemis brought them sudden death while giving birth. As was her brother, Apollo, Artemis was a divinity of healing, but also brought and spread diseases such as leprosy, rabies and even gout.
Artemis with her twin brother, Apollo, put to death the children of Niobe. The reason being that Niobe, a mere mortal, had boasted to Leto, the mother of the divine twins, that she had bore more children, which must make her superior to Leto. Apollo being outraged at such an insult on his mother, informed Artemis. The twin gods hunted them down and shot them with their bows and arrows; Apollo killed the male children and Artemis the girls.
Artemis was worshiped in most Greek cities but only as a secondary deity. However, to the Greeks in Asia Minor (modern day Turkey) she was a prominent deity. In Ephesus, a principal city of Asia Minor, a great temple was built in her honor, which became one of the "Seven Wonders of the Ancient World". But at Ephesus she was worshiped mainly as a fertility goddess, and was identified with Cybele the mother goddess of eastern lands. The cult statues of the Ephesian Artemis differ greatly from those of mainland Greece, whereas she is depicted as a huntress with her bow and arrows. Those found at Ephesus show her in the eastern style, standing erect with numerous nodes on her chest.
There have been many theories as to what they represent. Some say they are breasts, others that they are bulls testes which were sacrificed to her. So the true interpretation remains uncertain, we can say that each represents fertility. She carried to her own temple on her head as the protector of her own temple. But on the very night Alexander the Great was born in 356 in Macedonia, she could not keep her own temple in Ephesus. Because she was helping the birth of the important person. Later Ephesians understood it. When they told this Alexander the Great after his conquest of Anatolia, he gave the city special privileges.
Being associated with chastity, Artemis at an early age asked her father Zeus to grant her eternal virginity. Also, all her companions were virgins. Artemis was very protective of her purity, and gave grave punishment to any man who attempted to dishonor her in any form. Actaeon, while out hunting, accidentally came upon Artemis and her nymphs, who bathing naked in a secluded pool. Seeing them in all their naked beauty, the stunned Actaeon stopped and gazed at them, but when Artemis saw him ogling them, she transformed him into a stag. Then, incensed with disgust, she set his own hounds upon him.
They chased and killed what they thought was another stag, but it was their master. As with Orion, a giant and a great hunter, there are several legends which tell of his death, one involving Artemis. It is said that he tried to rape the virgin goddess, so killed him with her bow and arrows. Another says she conjured up a scorpion which killed Orion and his dog. Orion became a constellation in the night sky, and his dog became Sirius, the dog star. Yet another version says it was the scorpion which stung him and was transformed into the constellation with Orion, the later being Scorpio.
