Bear

In a Pre-Greek cult Artemis was conceived as a bear. Kallisto was transformed into a bear, and she is a hypostasis of Artemis with a theriomorph form. In the cults of Artemis at Brauron and at Piraeus Munichia (arkteia) young virgin girls were disguished to she-bears (arktoi) in a ritual and they served the goddess before marriage.

An etiological myth tries to explain the origin of the Arkteia. Every year, a girl between five and ten years of age was sent to Artemis' temple at Brauron. A bear was tamed by Artemis and introduced to the people of Athens. They touched it and played with it until one day a group of girls poked the bear until it attacked them. A brother of one of the girls killed the bear, so Artemis sent a plague in revenge. The Athenians consulted an oracle to understand how to end the plague. The oracle suggested that, in payment for the bear's blood, no Athenian virgin should be allowed to marry until she had served Artemis in her temple (played the bear for the goddess).

In a legend of the cult of Munichia if someone killed a bear, then they were to be punished by sacrificing their daughter in the sanctuary. Embaros disguised his daughter dressing her like a bear (arktos), and hid her in the adyton. He placed a goat on the altar and he sacrificed the goat instead of his daughter.
